I think that this review is pretty spot-on.
My thoughts on the game are:
1. The combat is mostly mashing buttons to kill mobs(not a bad thing when I'm just trying to relax).
2. The many puzzles were usually straight forward, though some solutions were not very apparent to a slightly inebriated twenty-something.
3. The dialog and jokes were kind of cheesy, but it's aimed at kids.
4. The movement controls ranged from decent to awful. The minifigures were usually easy to control, while the land vehicles ranged from good handling motor cycles to the truly awful go-kart(I spent a great deal of time retrying a 30 second race to learn how to use the damn thing). The flying controls are good for general use, but way too wonky for precision paths in time trials.
5. The camera views could be pretty terrible, which is partially why movement controls sucked at times. The flying time trials suffered the most from the camera view, since the next checkpoint ring could be very difficult to maneuver to if it wasn't directly ahead of the character.
6. The number of playable characters was amazing. My only gripe on this was having like 6 different Iron Mans and generic mob bad guys taking up space on the roster, when they could included some other unique characters.
7. They also did an amazing job on each character's animations. The way that the Iron suits take-off, the Hulk stampedes down city streets, and Archangel's wings flap as he flies(just 3 examples off the top of my head) are beautifully done. The smooth animations make just cruising around New York City entertaining.
8. The game froze from time to time. The playtime before hand seemed to range quite a bit, and it usually happened during graphic-intensive battles.
So yea, overall it's a very fun relaxing game, packed with quite a variety of heroes and villains.
Great review, Paul!
