This sort of highlights my issue with WFRPG, but in a different way.For me the appeal was the ability to play a "Started at the bottom now I'm here" Warhammer special character in a fantasy grimdark setting. Unfortunately the one time I tried playing, the other players were really into the OSR "every encounter could end with your character dying of sepsis, alone and unmourned. Just make a new one and don't get attached!" sense. The two sets of goals did not match well.
I've never been into any of the Warhams minis game. I run lots of OSR stuff in a low-fantasy, Early Modern Europe vibe.
What can I get out of WFRPG that I can't get out of OSR?
