In my own personal experience over the years, I've played a few superhero games, but they tend to be either one-shots of short campaigns (a few weeks) rather than D&D-style lengthy campaigns. I'm not sure why that is.
It's because the superhero genre does not lend itself to the mechanical advancement of a character. People love superheroes, and people want to roleplay them, but when you try to make it so they can level up, it stops feeling like superheroes.
But, in my experience, RPGs with no "level up" component tend to lack staying power. I understand this is a very broad statement, and of course gamers exist who love games without level-ups, but if you look at the big picture, I think this is definitely a contributing factor.
Also, while I admit that I haven't played every superhero game listed above, I have played more than a few, and I have yet to see one that successfully walked the line between too numbers-heavy (M&M) and too numbers-light (FATE). Marvel Heroic almost got there, but it's way too hard to teach, even if you're one of the few people who actually understands it.
Do any of these Bamfsies nominees fit the bill? I'd certainly be willing to look at a new one if it didn't suffer the same problems I seem to see in every superhero RPG I try.
