Beat-'em-ups too. I guess they're simplest genre to be good at, though I find most people don't realize there a little nuances to them that can improve your play. In single-player, it's all about crowd control and boss strategies. I like light gun games but never got to play any one of them in particular enough to really get good. I feel like I could have other wise. Played a lot of Virtua Cop at home, but with a regular controller (really wished I'd had a light gun), and mostly House of the Dead at the arcades. Love 3D fighters, but I'm mid at them. Beat a few shmups through persistence, but not good at them either. I'm pretty good at old-school side-scrollers like Shinobi though.
