I don't know about you, but I spent many an afternoon in high school and college playing Talisman. There was just enough "role play" for a lazy afternoon where your regular DM had to bow out or there wasn't a full group to conquer the next dungeon.
Talisman: The Complete Collection is available on Humble Bundle for the next 12 days as I type this. If you've never played Talisman and aren't looking to take a huge plunge, the core game is just a buck. If you've got the 11 bucks or so to beat the average price paid, you get everything - expansions, extra characters, simply extra of everything ;)
Did I mention you can get it in Windows AND OSX? Yes, as a Apple user I am very happy :)
