1. Dungeons and Dragons. That's the first thing that comes to mind for this question. Looks like fun, but I can never pull myself to play it. I always feel "fake" and weird when even coming close to the game. It's similar with acting. I've acted in a few plays growing up, and always felt weird/icky when doing it. But D&D looks like a lot of fun if I could get over that. 2. Programming. Did it when I was a kid. I just loved the idea of making my own video games, so I just dove in. Found some tutorials online and went to work. Ended up making a game a few years later (even though it was really fan boyish and crap). A few years after that, I've finally published my first "real" game. And I'm planning on going into the field for work.
Tabletop roleplaying games are crazy fun. I grew up playing them with a good group. To this day, a couple members in my group are ashamed of it, and don't like to bring it up in mixed company. It's a damn shame. Me, I created my own. I used a pen name, but that's mostly because I publish for my day job. I am a proud gamer. Congrats on #2. Post your game.
