I just tripped over this column where Comic Book Resources Twitter followers get to suggest things to a gang of waiting artists on a weekly theme.
Such as the reason for the stumble, Team-up or mash-up comic book characters with characters from Doctor Who! Which is, y'know, relevant to my interests. And a couple of those could totally happen, of course.
Anyway, there's also heroes out of genre and this week heroes out of time as also here. And if that Ancient Greek Hulk isn't tempting...
So take a look, see what you could crash your game into sideways.
