LOL! I'm sorry for laughing, but as someone who's had bad experiences with being set up with gamers in the past I have to say that you made the right decision

I consider myself as pretty geeky, but that's too much, even for me!
If I were you I'd send him an email though and be as direct as possible. I once refused to respond to a guy and he emailed me for over a
year on and off, asking what had happened. I've found that most guys will keep asking until they get a response. Probably the best thing to do would be to tell him that you don't think you have the same interests, and that you don't think it would work out but you wish him luck. If he pushes again, just tell him bluntly that you're not into the gaming scene and that it would be a problem in a relationship for you. Be very direct, or you might have him confused and hurt and wondering what it was that he did, which usually means a ton of communication from him. Maybe he'll learn something from it.
Sorry you had such a bad experience, but there are nice guys out there. I found my DB 4 years ago from an online blind date setup and he's a normal, great guy.
