Re: JAGS Wonderland: Just Wonderland
I'll second GURPS, as you can easily apply whatever fluff you want to it. However, it is fairly rules heavy, which may detract from the immersion required to have a good game of JAGS Wonderland. I'd suggest simply ignoring a lot of the more complicated rules, which really wont hurt anything and will probably make things run a lot smoother.
