I just don't see Champions of the Galaxy taking off as a superhero game. Not when it has to compete against HeroClix, or even Vs. Plus, "Champions" is already a pretty well-established superhero RPG brand; if anything, I think it will look like he's trying to Mockbuster off of that franchise, which will be more likely to piss a diehard player off, rather than suck them in. (To say nothing of potentially getting him slapped with a Cease-and-Desist Order.)
I got like, halfway through the story of this and just stopped. You can't write a superhero book without it being a comic, but that's just my opinion. I need a visual aid, dammit. The cards are cool, and if anyone could find a way to make bootlegs of this possible (as in printable PDFs), I'd be happy to crank out a ton of X-Men related cards/charts. I had a couple of guys done (Wolverine, Cyclops, Beast), but had no idea how to approach guys like Magneto.
I think from a bootleg perspective, the superhero version has incredible potential. Not a fan of the story, though.
