The Genesys RPG system supports gaming in any genere in any style. Of course, with something as broad as that, there's going to be a lot of ground to cover and a lot of things players can potentially want to do. You're going to need rules for some of those options beyond "wing it" or the generalized rules. Thankfully, Fantasy Flight is coming out with the Expanded Player's Guide to help out.
