We have both MCU and a wide assortment of Marvel continuities in outer_divide and either Phil or Jean would be awesome to have. MCU is currently Tony, Pepper, and Thor, and there's Loki here from Thor: Tales of Asgard (annoying but still basically good teenager). The mutants are Quicksilver, Toad, and Nightcrawler from X-Men: Evolution, Scarlet Witch from Wolverine and the X-men, and Molly Hayes from 616, so, well, at least everyone's used to the alternate universe thing? Anyway, the game has lots of plot but also lots of incidental hanging out, though as it all happens on a planet full of monsters and dinosaurs it's not exactly slice of life. It's a small game, maybe a little slow for what you're looking for, but really backtag friendly, and the AC's quite easy.
