Beat it.
Flight controls are tough to master but when you do...I want all superhero games to have these flight controls. It's actually a really good foundation for it (because some work is needed but its solid once you master it).
Graphics are nice on Iron Man on the rest...not so much. Especially since you'll be flying faster than the speed of sound and it goes by so quickly, or you'll be far away pegging them. Upon close inspection many models are not as good as the Iron Man model, probably for framerate issues.
Speaking of framerate there are hiccups in it, especially in the worst level of the game. Where you have to defend a reactor from dozens of helicopters, tanks, and power-suited men...while hundreds of cruise missiles are fired at the reactor. You're in the middle fighting enemies while dividing your time against hitting each missile. It's hectic and not fun, and when hundreds of missiles spawn and dozens of tanks and helicopters are firing their missiles....the framerate really starts to get chunky. But its the only time in the game where it hiccups. At least on the 360. I can't imagine the Wii fairs that well if that level's in their version.
Ultimately, its fun and you feel quite powerful on Easy, and quite weak on Hard. It's fun, easy achievements. The unlockable armor adds little but they do all have their own achievement thing to do (like Silver Centurion has the Old School achievement if you beat Iron Monger in it, Extermis gets an achievement if ground pound a tank or soldier while wearing it) and each suit has its own weapons, attacks, and defensive measures.
Favorite thing so far was the Hulkbuster suit which is slow as hell and flies poorly...but my god the damage it deals out. I took out one boss (a giant tank thing in the third level) with one attack. I was in awe. And the Hulk Smash achievement is fun to do.
There are three tilesets. Desert, which most of the maps are; Snow, which three levels are; and city which three levels are. Nothing destructible.
Solid fun once you get the controls down and you're off and running.
But its short. There is an unfair difficulty hick between Easy to Normal and Normal to Hard. The Missile level is poor game design. There's not a lot of variety between attacks, you have three kinds: Repulsor, secondary (missiles mainly), and unibeam from his chest. Punching is possible but lacks a lock-on making you flailing around more often then not. And don't ever try to punch a boss since there's no counter to their melee or their grappling moves which are unavoidable at close range and at least two of them will kill you one shot on Normal (Titanium Man and Iron Monger).
No multiplayer. Short levels. Short game. Fun though.
Which is why. I give it:
8/10 but no multiplayer and no real replayablity outside of unlocking armor which will take you a day or two at the most. And getting achievements...so....rent. Five day rental. You'll play, you'll enjoy (besides the missile mission, you'll hate that), and by day five you'll be ready to turn it in. I can't tell you to buy it because it's simply not worth the 60 dollars for 12 hours of game that you'll never touch again.
Likewise, if you ever see it for sale in a bargin bin for 15 dollars (sometimes you'll find some for 10) then pick it up. It's fun and maybe one day you'll be bored and want to fly around blasting people in the Hulkbuster or Classic Mark III armor.
The sequel needs to do what the Hulk game's sequel did. Abandon the movies. They tie these games down too much. The next one needs to add combos, different kinds of weapons, more attacks, better villains and better boss fights, more levels, and better cinematics and story.
5 Day Rent. Fun with problems. Low replay value.
