Just beat this and it was daaaaarn good. Best comic book game since the golden days of SNES imo. Game is very rough and can be glitchy, but the amount of stages and variety between each one is staggering. All the best marvel characters, lots of great moments, 25+ good boss fights with their own puzzle elements. Some parts are tedious and the combat is a notch below God of War, but the combat/platforming/puzzles/collectables all work together to make a great comic book title. Had a huge grin on my face for a good 70% of it.
If you ever liked comics as a kid or still like them now, then this is a must play imo. It's technically not as good as Batman AA, but I think it's a better comic book game. Plus it doesn't have stupid stuff like ROID JOKER FINAL BOSS.
