Ive been very very curious about GURPS for maybe a year now. Havent bought the actual book yet but i will eventually. Just seems to have so much freedom. Its hard to get my play group off DND though, its what they are familiar with.
as a newbie to the system myself I'm having a lot of fun with it! if you haven't heard of it I'd try the gurps lite version first which is free and a good starting point to add or remove rules and mechanics as needed.
