How many females do you know in real life who are really interested in retro games?
My girlfriend likes retro games, or at least playing them with me. Really old stuff mainly, she seems to like the SG-1000 games the best. There are tons of cute games for that system like Hustle Chumy, Girl's Garden, etc. Seems like girls and non-gamers in general tend to like retro games more than modern ones because they are colorful and fun, easy to pick up, and don't take a lot of time/explanation to get into. We'd have Bomberman tournies at my place all the time and the girls would always play.
