Every Saturday my wife and play roll playing games at a friends house. We started with Vampire: The Masquerade, then went to Middle Earth Role Playing (MERP), Dungeons and Dragons, and finally GURPS or Generic Universal Role Playing System.
We switched to GURPS because my friends wife got an editors job at GURPS and we wanted to support the company.I must say that I really like the system. It's really simple. Today I picked up GURPS for Dummies because I am still learning the system and it has some really neat reference cards.
You can also buy just about anything except the two core books in PDF form for a lot cheaper with no DRM.
Check it out if you get a chance.
