We play both board and card games that involve some sort of strategy component. Typically these games take 1-2 hours and are 4-5 players. Examples of these include Dominion, Agricola, Great Western Trail, Tzolk'in, Terra Mystica, Castles of Burgundy, Power Grid, etc.
If anyone would like to post comments about what games they'd like to play that night/solicit interest from other attendees, great to think ahead. No problem if not though, will bring a bunch of games, and everyone can just figure out what they'd like to play upon arrival. If you don't know games like the ones listed above but are up for learning, there are at least a few of us available to teach.
