As per title. I personally really enjoy deckbuilding / engine builders and civilisation games, but most of them understandably end just as you’re hitting the sweet spot of getting your engine up and running. Probably why Through the Ages is my favorite game - has all the mechanics I like, but lasts long enough that I feel like I get a chance to run them.
I love games that have different goals/mechanics/etc for each player. Even just different starting hands in a deck builder like Clank, or end goals like in Discworld.
