Marvel Rivals is, surprisingly, quite good. They're leaning heavily on the comics style for the characters rather than another half-assed attempt at an MCU adaptation. The game is entirely FTP, with only cosmetics being something you have to buy as far as I can tell, and you start with all characters unlocked with no bullshit. If capeshit (or, perhaps more appropriately, the source material that was turned into capeshit) is of any interest and you can stomach multiplayer PVP, I'd recommend giving it a try.
