I would say that you should find a way to play a few times to see what the experience is all about.

You might look for a local hobby store or book store to see if they have a board where folks post when they are looking for players or for games to join. You might ask around here or on other gaming message boards to see if anyone near you also plays. (It's a lot easier to learn when someone shows you, rather than trying to read about it.)

I would suggest you find a RPG that is simple and fits a campaign setting which you find interesting. Maybe get into the mood by reading books or watching movies on a similar theme to the campaign. Get together and play a few games and don't stress over the exact rules, but instead try to experience the fun.

If you want to look at Dresden Files, maybe download a copy of FATE or the Spirit of the Century SRD. Maybe support Evil Hat games by buying a copy of SotC (I really love my hardback copy!) and reading about how this kind of game is played.

It'll give you a feel for what RPGs are all about. Give it a shot!

Thanks, I appreciate that!  Two of my favorite characters to draw are Harry Dresden and John Constantine.  I'm working on another Dresden, now, of him making the trap for Toot-Toot.

I wish they were still doing the illustrations for the game!

This is my version of Harry on a stormy night, exhausted as usual.
