Boardgames

In my case, I enjoy marvel board games that bring out the characters' style a bit more than a skin on a good board game(already have plenty of good games). The already suggested Marvel Champions is a great coop where you play a single character trying to defeat the selected villain. I'll also put forth Marvel Legendary, it's a coop deckbuilder. If he has some favorite Marvel characters both of those games have oodles of expansions that you can mix and match.
