Go play every game you can in your area. Different games play different based on layout, maintenance, theme. You'll get a feel for what you like. I've bought games, and was sure I'd like them, only to either get bored quickly, or just not enjoy playing them. Sometimes you just can't get into a game for various reasons.

I picked up a police force awhile back just to scratch an itch, and loved it, once I got it shopped out, I hated the way it played. It was different, still love the theme...
