I don't know if anyone would have an interest in this sort of thing (I know that
Knight Dude
and
@JDCabrera are fans of Marvel, at least, but I don't know if they have any interest in the time period that I'm drawing from), but I've had an idea for an Avengers RPG for a while now, and I've finally made sprites for it. (all of the playable characters that I have planned, plus some villains)
My basic concept is that it's adapting the first 16 issues of the Avengers (plus a handful of other comics that overlapped with those, like two Fantastic Four issues that had the Thing fight the Hulk, or Avengers 1.5, which was drawn by Bruce Timm of Batman: The Animated Series fame and works as an excuse for me to fit Doctor Doom in there), though your actions can alter the events of the story. (for example, Thor or Iron Man could leave the team around issue 7, or Hulk could rejoin the team if you take certain sidequests)
I'm not sure how the sprites turned out (they're based on Shining Force, but I'm not a fan of how Wonder Man's visor wound up), and some of the characters seem like stretches (Blue Marvel's backstory has him active in the 60's, though that's a retcon; Captain Marvel's backstory has been retconned to the point where I can justify it, but I'm worried if Spider-Woman might be pushing it in terms of the timeline), but I'm glad that I've accomplished this much.
