Mark G. said: There's a few different STALKER RPG systems out there, if I remember correctly. A generic Google search comes up with a number of results. (" <a href="http://1d4chan.org/wiki/STALKER:_The_RPG" rel="nofollow">http://1d4chan.org/wiki/STALKER:_The_RPG</a> " for example) The best thing about Roll20 is that it's entirely system agnostic. It doesn't matter what rule-set you're using, you can make it work for you. I've seen full-on board games and card games along side more 'traditional' table-top RPG's Hmm interesting, I just googled it my self and I was hoping for a more official game. I guess gurps could work to bad I've really tried or played GURPS.
