Honestly, I think the market is so saturated with superhero media (movies, games, tv shows) that anything that’s not at the top is at the bottom. I kinda know that Green Arrow is a superhero just from what I’ve heard and seen in other superhero stuff, but that’s about it. Most people that aren’t really into the superhero genre won’t bat an eye unless they market it as the next best AAA game, and then if it falls short of that it’s a bust.

Edit: it may be better off as an indie-style, lower budget game that the fans can get into without the producers having to risk a whole lot, but with the whole Marvel/DC stuff they seem to have huge budgets and bigger profit expectations.
