Hnnm. I'll give a tip for those guys who are drastic gamers, and wouldnt spend time with their girls in real life.
Step one. Make a T-chart, and list all girls in your classes' names. Step two, ask them if they like videogames on the PC or whatever stuffforget console, and chop off those who dont like games, and if they like all the games you like, or close, godatenao.
