I buy way too many games, but a few have been rising to the top lately.
Aside from Gloomhaven, which is our #1 game when our party of 4 are all there, Charterstone has been a fun legacy game.
Clank! is an excellent game that can be done in an hour and is easy enough for everybody to learn. Card/Deck builder for 4. There is a sequel for the more serious gamers called Clank! In! Space!, but takes longer than the original
Century Spice Road is a good quick 5 player card game.
We just got Rising Sun off of Kickstarter and that is a very fun one for 4-6 players.
Also just got a party game called Muse which is quick and extremely fun for all.
2 similar games have potential as well, just haven't played enough yet, Stuffed Fables and Grimm Forest. Nice theme and packages.
