Went down to the LGS to pick up some Sternguard and Death Company, but got side tracked and ended up leaving with https://www.fantasyflightgames.com/en/products/warhammer-40000-conquest/ http://www.worldofmunchkin.com/game/
as well as my fill in Assassin in 40k games
I also played Fluxx. That was hella fun. I'm going to have to pick that up next time. The game is really simple, the rules are 3 cards in hand at start of game, Draw 1 card and Play 1 Card. There are cards that modify the rules, such as drawing more, playing more, hand limits, etc. There are also cards that modify the victory conditions, as the game doesn't start with any. I played the Sci-fi version, although there are numerous varieties.
