Marvel Heroes

It astounds me this is somehow from the same devs that made Diablo. There's no real level design here at all - it's mostly large empty fields with hordes of weak, braindead enemies that charge at you. The hero kits were mostly just dull AOE attacks with character building centered around boring stat boosts. The bosses are one-dimensional damage sponges with simple, easy to dodge attacks and gimmicks. The actual multiplayer aspect was an after thought and you were better off going at it solo.
