Roleplaying games are lots of fun. I should know, as I've been playing them for literally decades. And I've played with a lot of new players. Some have taken to it readily. Some really liked the idea, but the systems we were using were a bit complex for them. Thankfully, there's a new RPG system coming out that's designed specifically to bring new players into the fold. It's called BaG, which stands for Basic and Generic, and it's up on Kickstarter now.
From the campaign:
The campaign's up and over its funding goal (being fair, they weren't asking for much) with 23 days left to go.
