Nah, I’m really not a GURPS fan. Besides some of their sourcebooks I grabbed as general resources, I have a single 2Ed core hook because I was in a group in the early 1990s that played GURPS as one of the top 3 systems. IOW, it was purchased out of convenience.You're a Hero guy, though. In terms of system and ethos, you're maybe two beers away from a GURPS dude.
(I say with love for both systems)
