No probs! Warhammer as I know it is a game where you move armies of really expensive miniatures around a board using a tape measure, and positioning and terrain and that sort of thing makes a huge strategic difference so doing it through text would be...pretty bad at best.
I'm probably biased but Pathfinder rules can be modified to any sort of universe you want, making it really useful for forum dice games. Then all the resources and campaigns can be stitched together to help build your world and run it. Definitely got some reading ahead of you if you want to run a game though.
