I see you like cooperative games. Have you given Sentinels of the Multiverse a try?
I point this out because the Kickstarter for the latest and final expansion has a really sweet deal for newcomers. Granted, $399 sounds really daunting, but it's a pretty sweet package. You'd have to know if you like it first, though. You can also buy the digital copy of the game. I think there's a free version with limited selection.
I haven't pieced together how much that everything ever bundle would cost. The everything everer probably wouldn't be worth it; at least it doesn't appeal to me. But each expansion is about $30-$40, and there are five expansions. Each mini expansion is about $5, and there are at least 15 of those in this bundle; I lost count. The storage box is $60, which yeah sounds super expensive for just a box, but trust me when I say it gets old lugging multiple boxes of cards around. Wait a sec, you're on the Dominion board; of course you know what I mean.
Anyway, really pricey, especially for a birthday gift. But if you know you like the game, this would be a blast.
