Well, the reviews are in, and it does not look good. Ign gave it 3.8 out of 10. Ouch.
Here's an exerpt from their review.
The problem with Iron Man is that at some point someone sat down and said "You know what would be fun? Drop players into situations where they have to do repetitive, meaningless tasks and then add respawning, overwhelming douchebags." That's a shame. Flying is fun, the upgrades are neat, and the game can look good. However, these pros are outweighed by the aforementioned frustration, crappy storyline and lame cutscenes. You never feel like Iron Man in this game, and if you're like me, you never feel like you're having fun.
