Lots of interesting systems here. I'll have to check them out. To mention Masks again, it isn't really a system that can be min/maxed. A different powerset (superstrength vs. martial arts) doesn't really mean anything mechanically, and failure and vulnerability are the only avenues for advancement. Like Paradox alluded to, it's a system concerned primarily with progressing narratives through character growth and relationships/bonds.
That said, I'm not sure how it'll work with a game that has adults and teenagers, which is where I'm seeing the most interest. Its main theme is finding identity in a world where everyone is trying to influence you. Not to say that adults are completely grounded in their identity, but a lot of moves would have to be renamed, at least.
Regardless, it's been pretty validating seeing people excited about the idea. I'd run a game like that myself if I had any coding skills whatsoever.
