I guess I should start with that since I am the hola hf greeting guy on isotropic.
Other than that, I am another that lives in SoCal. I play a wide variety of games (current favorites other than Dominion are Agricola, Small World and Citadels though my all-time favorite game is Wizard) and have since my time in college at Auburn.
Favorite Card: Monument (for now)
Here on the forum I post every so often when in the mood but tend to lurk quite a bit. I also won the Kingdom Design Challenge and since I had all the sets I sent the Base set to my parents (they already had Intrigue).
I'm happy to play with anyone here and for those in SoCal who might be interested in any sort of games, you should come play IRL with my group. We play something (The current favorites, Dominion, 7 Wonders and Thunderstone right now) most Friday nights late into the night.
