Edit: let's post something on topic first.
So the game that was cancelled was obviously MegaMan Legends sequel from what I know MM Legends is basically MegaMan in 3D. Where as Mighty#9 is a sidescroller like all other MegaMan games.
I wish studios like Capcom and Sega would be more liberal at economically licensing their franchises to the talent that helped create them. That way, they won't have to clone their own franchises.
Capcom and Sega have a history of suffering from clones.
The creator of Street Fighter quit the company and created Art of Fighting, which is why Ryo is an obvious clone of Ryu with significant differences made to prevent Capcom from suing them.
Then we have Sega who currently have Mizugichi cloning his creation Rez with Child of Eden and the upcoming Panzer Dragoon clone that I can't remember the name off.
