Inspired by the favourite expansion thread, and because we (Peppy and I) were getting a little derailed in discussion regarding Cornucopia, I've decided to make a thread.
Here was the discussion we had so far.
...
It is also the set I feel most comfortable recommending to any new player looking to get into Dominion beyond the base set.
...
I'm not trying to make an argument against an opinion, but why is this? I'd say it was one of the worst expansions to get as a first one, perhaps ahead of only Alchemy and maybe Hinterlands (I assume you mean Base game+1 expansion).
The high power cards will lead regularly to games being Cornucopia heavy, as base game is on the whole weaker on average. I don't mean there'll be more Cornucopia cards, just the ones there are will generally be the most important by a moderate margin, which isn't really good in my opinion.
The cards are a reasonable bit more complicated than those in some other expansions, in both effect and strategy. Sure, adding new complex strategy is fun, but as a first expansion, I'd say go for the medium level complexity first.
It's a small expansion and moderately new, meaning it's probably the most expensive expansion per card. Perhaps this is a matter of opinion, but I'd more strongly recommend a better value big box, and add a small box or two when they just want something to keep the game fresh.
So... yeah. In terms of recommending expansions, I'd probably suggest Intrigue first (for the extra base cards - a reasonable number of face to face games are in bigger groups, I find), but if the base cards are unnecessary, probably Seaside next, then Prosperity (Colony and the like are great, but with just Base+Prosperity things get a little top-heavy in terms of cost, I'd say).
If someone were getting two expansions at once though, I'd probably be more willing to recommend Cornucopia... the extra complexity and power surge gets hidden away a little.
Yeah, I probably shouldn't have said this without explaining it, I just didn't want to derail the thread - so, overlong off-topic 100% opinion-based ramblings ahead! I feel bad, there is probably even a thread for this already from way back when (edit: well, I checked, and apparently there isn't one). I know this is crazy long; having friends that have often asked me this question or that I've introduced the game to means I've thought about it a lot, and I'm really bad at condensing things. A big factor in my opinion about this (and it is just an opinion, and a biased one) is based on 3-4 player games IRL and playing with new players who are usually resistant to brutal attack cards. YOU HAVE BEEN WARNED.
I do agree that Alchemy and Hinterlands are the worst sets to introduce to beginners - Hinterlands for having way too many different mechanics for new players to really understand what they're doing, Alchemy for being so brutal and action-chain oriented. I personally got all the expansions in order, and I don't think that's a terrible way to go, but I don't believe that it's the very best way to ease people in.
If you need the extra base cards than Intrigue is really the only choice, but assuming you don't I can't really get behind it recommending it as a first expansion. The biggest problem is one it shares with Seaside: brutal attacks that stack nastily in multi-player. Intrigue has Torturer, Saboteur, and Swindler; Seaside has Pirate Ship, Cutpurse, and Ambassador, and that's ignoring non-stacking but still horrifying stuff like Sea Hag, Minion and Ghost Ship. Speaking from experience, all of these cards can easily make four player games (God forbid 5-6) infuriating to the point that I've seen new players give up on the game after one go. Besides that, Intrigue's "choices" theme is a great one, but it isn't the most inviting to players used to the relative simplicity of the Base set. Pawn, Secret Chamber, Masquerade and Minion are all cards I dread showing to new players - the former two have lead to some of the most aggravating games I can remember. Choices that effect other players are obviously a huge part of Dominion, but Intrigue throws a ton of them at you all at once. Seaside and Prosperity both add plenty of mats and tokens and other things to keep track of, not to mention the duration mechanic, which is awesome, of course, but forces a lot of "wait, so how many actions do I have now?" kind of questioning. All of those things are sure to overwhelm coming straight from the Base set,
Soooo, finally, why Cornucopia? For one, I kind of like the idea of starting newer players out with a smaller set. That's probably just personal preference, but when all you know is the Base set it might be better to bridge the gap with a manageable amount of new stuff and then ramp up to the big guys. It helps that for all of Cornucopia's perceived complexity, it's really a pretty simple set, if not to play strategically then at least to understand quickly. Remake, Hunting Party, Young Witch and Fairgrounds are all somewhat self-explanatory variations of Chapel, Lab, Witch and Gardens, Farming Village is going to confuse a new player less than, say, Mining Village, and Fortune Teller is one of the simplest attacks in the game. The overall theme of variety is really easy to grasp; it only takes a successful play or two of Menagerie or Harvest for anyone to get the basic concept down. Horse Traders is a much simpler reaction than something like Secret Chamber, and unlike that card is an actual counter to Militia. Hamlet is similar to Pawn but with half the choices and the ability to draw a card before a decision is made - a much better introduction to the concept of choices, I think. Jester does a great job of solving the 'stacks in multiples' problem of the other sets' more brutal attack cards, still being much better in 4 player but balancing that out with a nice dose of luck. That leaves Tournament and Horn of Plenty as the only cards with real possible learning curves, but their uniqueness is a good thing.
It takes some time to play Cornucopia's cards optimally, I'll give you that. You could say the same of any expansion. But nobody is going to read them and be confused about just what their purpose is in the same way they would for several of the cards from other sets listed above and plenty that I haven't even mentioned. It's not going to turn people off thanks to powerful attacks. It adds few difficult to understand concepts or foreign choices, no mats, no tokens, no dual-type cards, no clutter, only prizes. It bridges the gap to Prosperity by introducing just one Kingdom treasure card (not counting Diadem).
Quick Edit: You mentioned Cornucopia being a bit too powerful, and it maybe overwhelming the Base set cards. With a couple exceptions, I don't think it's a much bigger leap than Intrigue or Seaside, less of one than Prosperity, and it has the added benefit of encouraging variety, which means that in order for a lot of Cornucopia's cards to actually be powerful you kind of have to incorporate Base set stuff.
I agree with some of those attacks. Ambassador, Sea Hag, Pirate Ship (for new players) and Ghost Ship can all be problematic for large groups. In Intrigue, Minion is less of a problem (beginners don't get why they're so good, and in multiplayer... they're still not), but Torturer, Saboteur and Swindler, yeah, I can see the dislike for them. So in terms of attacks, yes, Seaside and Intrigue can lead to some nastier games.
Regarding mats and tokens... sure, you can construct a game with all the crazy new confusing mechanics at once, but in all likelihood you'll see 1-3 duration cards and perhaps one mat or token card, if that, when you first introduce seaside. I don't think it's that complicated at all. And the only issue I've ever found with durations is remembering to keep them out and do their thing, tracking isn't an issue so much (there are worse cards for tracking... Hamlet.). Prosperity is even more tame, there's one card with a mat, and three with VP tokens. You might see one, maybe two, and the VP tokens take one or two plays of the card to understand what they're doing. Not a problem.
Again, small set vs. Large is probably a matter of preference. If it was someone just looking to make the game a little more exciting for their occasional plays, I'd agree with small set. But otherwise, if it was someone who was likely to play a lot more Dominion I'd definitely recommend a big set. As for Cornucopia's cards:
Remake: You brush this off as simple, but the trashing exactly two and gaining cards costing exactly one more is slightly confusing at first. Moreso than say Upgrade, which is just one card.
Hunting Party: It's easy to make mistakes with this (I still do) as you have to do quite a few things with the card - draw, then reveal your hand, then reveal cards from deck, then put one in hand. Easy enough but a little complex.
Young Witch is... not simple. It has weird reaction timing, it has weird setup rules and you need to mark that Bane somehow. It's hardly a self-explanatory version of Witch.
Fairgrounds is generally okay, but the granularity of it's points can throw people.
Farming Village I don't think has much on Mining Village, a little simpler but they're both simple cards.
Oracle too.
Menagerie is pretty straightforward, although it's a little confusing to have say Menagerie/Menagerie/X/Y/Z and get the +3 card bonus.
Harvest is simple, yes.
I don't think Horse Traders is really any simpler than Secret Chamber. Easier to see why it's useful but not really easier to use.
Hamlet has tracking issues for buys and actions, which can get very confusing. Pawn is just as bad, but most of the time your Pawns will do very similar things. Hamlet tends to be a little worse for me in that regard, so I'd be a little more afraid of using it with newbies.
Jester is simple enough, I guess, after you've played it once or twice.
So I think there's more than just Tournament and Horn which are confusing. Most of the set can be confusing in some way, especially to a beginner, but notably, Young Witch and Hunting Party are also somewhat difficult to grasp.
I have to admit, there's less of an issue there than I thought... it's mostly just I dislike the set I think
. Well, dislike it being overpowered in general at least. I think it is much worse than Seaside, Prosperity or Intrigue - Remake, Young Witch and Tournament are considered three of the best $4's, Hunting Party is one of the best $5's, and Hamlet is one of the best $2's - that's 5 cards out of 13 considered in the top ~15% of their price range (it doesn't take a lot of work to realise that you'd expect about 2, so that's twice as many power cards as you'd expect!). I was definitely extreme saying it would overshadow the base set, but considering the base game has perhaps... two of those same high level power cards (Witch, Chapel), you can see Cornucopia will often be the main player in the games. All things considered... I think I might recommend Cornucopia a little more highly now, or at least, small expansions more highly.
