This just highlight the artistic decline the video game industry is trapped in.
The MCU has been the biggest thing in pop culture for a decade now. Given how high profile the Marvel movies are both the casual and the hardcore gaming audience would be very easily sold on an Iron Man game or a Captain America game. They've had a full decade to capitalize on the MCU's popularity but the gaming industry seems unwilling to do it. The only ambition they had with the MCU was to make a mediocre live service game steeped in outdated and discredited design philosophies. The industry had 10 years, dozens of movies, six main Avengers, several side heroes and countless settings and genres to work with, but an outdated live service was all they wanted to do.
Its the same as Star Wars. Before the sequels became controversial there was a perfect window to heavily capitalize on the desire for Star Wars content but all EA wanted to do was release two mediocre shooters which they then sabotaged.
I'm sure that somewhere in the archives of game companies there are pitches regarding all sort of Marvel and Star Wars games but that since they weren't a live service the game industry was avoiding all those pitches like the plague. Once the life service gimmick ends it might start to become apparent just how many good games we missed out on.
Eh, they did do some games for the initial batch of films too. (And countless Lego Avengers games).
I wouldn't entirely put this on the game industry either. Because the old House of Mouse is notorious for lackluster investment in its gaming licensees, and for being hyper-controlling about all its IPs in general. All those other ideas were probably equivalently shutdown by them because they either didn't fit their storylines, or they only wanted tie-in games and with the MCUs (massively bloated) release schedules, actually getting a game that isn't just throwing assets on existing ideas is rough.
Star Wars actually gives us a case in point. The "good" (ish), or at least unique Star Wars game.... was Fallen Order. A (probably) non-canon (or well, it was neatly wrapped up so it never need be referenced) story, featuring basically no established characters of note, with a pretty obviously lower AA level budget.
Disney won't throw in and put their support (and their A-list) into anythign that isn't going to mill money back, even if they do let the brand on it.
