Lol op literally described X-men mutant academy. It was the original game that came before the ultimate alliance games. You created a new mutant and fought alongside the X-men. There was time for role play in between missions. I don’t remember if it had classes or not but adding something like what was on fire emblem 3 houses would be cool. I would also say midnight suns borrows heavily from it in turns of Roleplay interactions with the hero’s. Game had a lot of kinks and they decided to take away the custom new hero when they shifted to the ultimate alliance games. Definitely worth still playing if you can get past the dated graphics. Ultimate alliance 2 however was nearly perfect in terms of rp, combat, and skill progression.
