I love this question. It's like a nerd My Fair Lady--how do you bring out his latent geek? The raw material definitely sounds there. But how do you mold him into a Wii-playing, zombie movie-loving Eliza Doolittle? (Er, perhaps I took that reference too far.)

First off, I would find out what sort of games he really likes to play. Is he a "shoot-em-up" guy, or does he prefer the more family-friendly charms of Wii Sports and Mario Kart? Maybe you could mix in a few games that match his interest (these days, there's a game for pretty much everyone) the next time friends come over. For example, I love Rock Band. Some days, it's all I can think about. My girlfriend likes it fine, but, overall, she could probably take or leave it. However, once the Beatles version came out, all bets were off-- she was hooked. As a huge Beatles fan, the prospect of playing "Ticket to Ride" and "Eight Days a Week" suddenly transformed her into a huge video game nerd.

Also, perhaps you could mix things up on your Saturday night geek-a-thons. Does he like card games? Apples to Apples is pretty much the perfect party game, and a good gateway drug to the "harder" stuff. (Like, say, Risk.) Or what about movies? Ask him if he wants to host a sci-fi movie night for your friends, and let him pick out the viewing selections. (If he needs some ideas, tell him to go here.) The idea is to make him feel like he's part of the evening's festivities, and not just doing it for you.

Ultimately, though, it's okay if he never fully lets his geek flag fly. Maybe that's just not who he is; and perhaps it's what attracted you to him in the first place. Surprisingly, most of the women I've dated aren't all that geeky. Sure, they might be really passionate about, say, the band Pavement or Sex and the City. But most of them wouldn't define themselves as geeks, and have tended not to love things in the sci-fi/comic book/classic video game realm as much as I do.

Hey, as the great philosophers Paula Abdul and MC Skat Kat once said, "opposites attract."
