This was pretty quick to judge. I guess there's a meta-lesson here compared to my judging on 'wonders' - simple mechanics are easier to assess.
Town Centre NoMoreFun
This is a really solid, simple way to demonstrate the Route mechanic- you can get that village right away, it synergizes extremely well with $4-gainers.

I feel like this is one of the sadder entries - a more expensive estate that can sacrifice itself. That low-VP / low-cost region is tough to build in due to things like Tunnel being 2VP for $3. I think letting it trash any Victory card for +2VP might be a way to salvage it - sort of a mini-Farmland then, where it can help deal with your starting estates.
Trade Fair Xen3k :: Withdrawn
I know this wasn't your entry, but I actually really liked this one, especially the old version - drop the +Action, so giving villagers isn't as automatic, and it becomes a very interesting card. I hear what segura was saying about giving routes as the "easy mode" for it, but i suspect that will only go so far in a game with junkers or a game with solid kingdom treasure options (gainable ones like Stockpile) that someone else can get and play right away.
Guard Tower X-tra
This is an interesting riff on Familiar. I think it's way too powerful for $5, even if it doesn't scale well in a deck (ie, having multiples hurts its attack ability, not "it plays differently with different numbers of players"). It's interesting in a "I don't know when I'd want to use this" way. But yeah, I don't know if there's a good price for this to be. $5 is too cheap - compare/contrast with any of the $5 peddlers - and $6 seems too expensive, considering it helps other players/doesn't scale in-deck.

I like this. Good use of spoils, good use of Routes, not busted if you open double, this is really nice.
Naval Charts Xen3k
I am a sucker for overpay effects. I think you'd almost want to make this a $3+overpay event, since (situations where you care about the +Buy aside) you just want the tokens and would spend an extra $1 to trash out the charts themselves. Still, this is a novel way to do this.
Ore Gatherer fika monster
I think segura's right on this, it needs to be a $5, solely because Explorer is a $5. If you dropped the silver gaining, I could see it at $4. Or if you break design protocol and put the silver gain above the Route gain, so that you can't always gain the Silver to-hand.
Roadsmen The Alchemist
I get that we're living in a post-Menagerie world and there's now plenty of ways to get potion and debt cost cards in your deck without paying for them (kiln, transport, disciple, etc). However all of those are multi-step processes. This just gains City Quarters, full stop, with no penalties. It even gains them to your hand or top-deck. That's something that should be patched or fixed.
Tinker Timinou
Tinker has some interesting synergies - gain it, get a curse to the top of your deck (one of the routes), spread the love around with this - but I'm pretty confident this would be a hubris card. It's too many steps to set up (although the route tokens can help with this), and/or the blind remodel is going to hit your province, same as the zombie mason.
Master of None mathdude
I was ready to tear into this for being too similar to JoAT, but honestly, the only change I'd make to it is getting rid of the remodel to just say "you may trash a Curse or Copper" or "you may trash a card whose cost is $0". The $1 step isn't broad use case. I like that this can gain the $3 card to hand but that acts against the draw-to-5 aspect. Really well done.
Usher DunnoItAll
So this is good at running down piles. And general from-trash-gaining. And making you take VP in exchange for routes. But I'm not sure when I'd actually buy it. I'm interested to hear what you think the use case for this card is; personally, i'm not sold on it, and I think it'll be a dead pile (especially being terminal) most games.
Without further ado:
