I don't see any reason to be mad. Miles is a great black male character who is carving out his own space in one of the largest franchises on Earth. It shouldn't have to be an either or situation. Miles getting a game and it being a massive success could very well inspire Marvel to see potential in a Black Panther game. Personally I think characters immersed in fictional worlds (BP and Thor most notably) have the most potential for video games because you can do a bunch of epic worldbuilding like Elder Scrolls. Even if they're not as storied as Spider-Man or Batman, the fact they live in places so far removed from the rest of Earth means you can really dig into lore and do reinvention of rogues and concepts.
