I'm a 2e guy, mostly because I got comfortable with the system (and also didn't want to pony up for another set of books. :)  )  But if you're looking for RP heavy, do you want a big. complex system?  I really like MM, but it can bog down PbP games, especially in combat...

I guess it really depends on the way you define RP heavy. I want to put more of a focus on things OTHER than combat. Yes, combat can -- and should -- exist at some level, but there's more to the lives of people in a universe with superpowered people than just punching each other senseless.

I chose M&M because it's what I know and understand. I could be convinced to go with something less complex, but I'd very likely become frustrated with the system if and when things didn't work the way I expected them to.
