I enjoyed the Avengers game, I would recommend it to any Marvel fan. Most word of mouth was about the live service portion and how boring it ended up being grinding slightly randomized instanced missions at the endgame, but that's not all there is to it... There's an entire singleplayer campaign with a fairly lengthy story and cutscenes and Tomb Raider-like exploration/platforming/puzzles between combat encounters (it's made by the same devs, after all). It's a no-brainer at only $4, buy it now because it's being delisted at the end of the month. It will remain playable after that, they're just done supporting it.
