Welcome, the EM guys are a lot of fun and generally laid back.
Reviews can give a good general feel, but what appeals to one guy doesn't always work for another. And vice versa. One thing I've learned is games will never stop surprising you. A lot of games that I didn't think would be for me turned out to be great fun. And some games that everyone seems to love didn't impress me that much. As mentioned after awhile you get a good general idea of what games you will like. The more you play the better an idea you will have. I think they are having the Tom Taylor open house during MGC this next time around. That is the best local place to go to play a ton of EM games.
