It's like a video game, but really slow and you have to buy thick books full of rules so you can argue on forums.

Trying to explain roleplaying games with a transcript of play is the worst possible way to introduce anyone to the hobby. RPGs aren't a spectator sport, and the enjoyment derived is purely through participation. Every time I read one of those transcripts, I envision how I'd react if I knew nothing about RPGs...and cringe. "Nerds talking about non-existent bullshit." Yep.
