We haven't had a Zweihander RP here I don't think, but there have been a good few Warhammer Fantasy RPs. Right now I think all the Warhammer RP stuff going on is in the SciFi version, 40K, but a lot of the writers for 40K also like to write in Fantasy. Maybe check out Deadlands too, since you like low tech and fantasy stuff. It's basically Weird Wild West stuff. Cowboys and Zombies and Voodoo and Other Vengeful Spirits. Anyway, there's a pretty good relatively steady supply of RPs here. If you don't find something you want to join that is still accepting folks try to keep an eye out for writers you like. It's a good way to start getting involved, if there's not just an RP you're ready to hop straight into. Welcome to RPG, good to have you.
