Action platformers because they're simple. Usually only requires a couple buttons to play. I don't have to memorize a million things to have a good time. They're easy to pick up, challenging to master, and I like that. I can just pop it in, play a few levels, then quit. It doesn't feel like a huge commitment.
This doesn't mean I don't play other stuff as well, but platformers will always be my favorite. :)
