My biggest bugbears about MvC:I's roster were that 80-60% of the cast were returning from the last game, and that there were only thirty characters at launch. Granted, that was all due to the fact that the game was a poorly-funded rush job forced to coincide with a movie launch. So I decided to transport my mind to an alternate reality where Marvel was more sensible and, while still wanting to have the game match up with the MCU, gave Capcom a lot more time and money to do their thing. Based on that premise, here's what I did:

* I bumped the roster up to 40 characters, 4 more than vanilla MvC3.
* I whittled the roster of returning characters down to 20, with 10 character a side. I tried to focus on those that I thought would provide some variety of playstyles as well as being general fan-favourites that people would like to see come back.
   * Frank West got the boot because *fuck him*. He stopped Leon from being in a game.
   * Spencer got upgraded to his superior (imo) Rearmed version.
* I added in the newcomers from the original MvC:I back, while adding in new characters that I felt would be interesting and well-received to get a round 20 each side. I mostly focused on the characters that would have been relevant during the late 2010's in time for Avengers: Endgame to come out. The new characters I added were:
   * Daredevil, Loki (Marvel)
   * Nero, Rashid, Ruby Heart, Gene, Juri, Asura (Capcom)
* The rivalry matchups were based on official art depictions from MvC:I, with tweaks to accommodate the missing characters and newcomers.

I'm not entirely happy with this. I don't like that Winter Soldier is here because he's my least favourite Marvel character, and I wish I'd been able to get a few more out there or colourful picks in there. If I had my druthers, I'd have added Phoenix Wright in there, as well as maybe Maximo, Regina from Dino Crisis and a Power Stone or Rival Schools rep. And there's at least one or two Marvel/MCU characters I wish I could have added. But I was working with an (admittedly) flawed premise, so it is what it is.

Let me know if you think I did a good job or not.
