What Games Do You Play?

So my son is into Bakugan. I've never played it. I understand the game and the concept, but for whatever reason it just doesn't interest me. Which is kind of odd because I do play quite a few games.

I like Magic The Gathering, and have a passing interest in Pokemon. I also enjoy a variety of video games including Guitar Hero, the Fallout Series as well as Warcraft and Starcraft. So I'm into games. Not everyone is. I understand that.

What makes a person like one game and not another? Maybe I'm just getting older now and things that I would have enjoyed even a few years ago are being swallowed up in the ongoing rush of life and continual pursuit of comfort.

What about you? What games do you play?
