No worries, I'll house rule the "crap outa"* the system and share what I have here,I'm backing the game almost exclusively for the setting, along with the interesting campaign rules presented. I'm personally not convinced the core game system from Mutant will fit a fantasy setting, since I prefer game systems with more attributes and skills. In my experience roleplaying in fantasy worlds usually requires more complexity, otherwise player characters tend to end up feeling generic. I'll give the system a go of course, and see how it feels, might be you find the sweet spot!
You share the same concerns, you are thinking long term,
