Hey, I figured since I was the guy barking about this on the forums when it was announced, I would go ahead and submit my review of the game since I have played and beat it. So here goes.
Marvel Ultimate Alliance. A game? Sure. But it's also something more. It's a comic-book geek's wet dream. I mean X-Men legends 1 and 2 were fun games, but they excluded a lot of the things that are great about the marvel Universe. Namely, everyone that isn't a mutant (Juggernaut and Iron Man aside). Now we have an almost completely new cast of Characters to play with, and they're all the good ones. The only major heroes this game was missing were the Punisher and Hulk as far as I can figure. This all adds up to awesomeness. 100% sheer awesomeness.
You start the game on the sheild helicarrier, fighting ultron robots and doombots as Spider-Man, Thor, Captain America, and Wolverine, however as soon as you get to the first save-point, then you can really start making your ultimate Marvel Team. Right of the bat, the heroes available to you are vast in number. Ms. Marvel, Iron Man, The Entire Fantastic four, Spider-Woman, Deadpool, Thor, Captain America, Spider-Man, Wolverine, Storm, Iceman, Elektra, and Luke Cage are now at your fingertips. It's so much to process, you'll have to play the game at least twice to really get a feel for each character. Later on in the game you unlock Dr. Strange, Blade, Ghost Rider, Black Panther, Daredevil, and Nick Fury as well. I played the
PS2 version of the game, which means I missed out on some characters. PSP exclusives: Black Widow, Hawkeye, Captain Marvel and Ronin. Next-Gen (Wii / PS3 / XBOX 360) Exclusives: Colossus and Moon Knight/Khonshu. There are so many characters to play here, it's makes you feel guilty to build a team of only four people, since you feel that this amazing gift activision has given you is going somewhat unused. On top of this, Every character has 3
alternate costumes, which in some cases, are completely difference characters (with the same powers) such as Ghost Rider / Vengeance / The Phantom Rider, Captain America / U.S. Agent, Thor / Betta Ray Bill, Ms. Marvel / Sharon Ventura, Spider-Woman / Arachene / Spider-Girl, Iron Man / War Machine and Moon Knight / Khonshu. Anyway, the Character Selection is just the beginning of the awesomeness. Onward to melt-your-face glory.

The gameplay in this game, although somewhat repetitive, is quite fun, especially when you have friends doing it with you. All the characters have a good selection of powers / moves you can choose to equip (in the wii version of the game, you will be able to use all without equipping them due to the unique control system!). Not all the moves are necessarily good ones though. I found it much more useful to just stick to your guns (in some cases, a-hyuck!) and just concentrate all the skill points you acquire on making the moves you have completely tricked out. This way, at the end of the game, you are literally wading through your enemies (even bosses!) on your quest to stop Doom from destroying the Universe. In case you were curious, by the end of the game my team was composed of Deadpool, Captain America (with the U.S. Agent costume), Ghost Rider (with the Vengeance costume), Blade, Nick Fury, Black Panther, Spider-Man, Daredevil, and Iron Man (those are in ascending order of use too, most popular to least).
You storm through the halls of Valhalla like you were in a Dragonforce Music Video, you tear through murderworld like the punisher with an intense hatred of clowns, you kick Shi'ar butt with Corsair as if you were screaming JEAAAANNNN in the 90's X-Men Cartoon show. Ok, I had my fun, now you get the rest of the locations without cheesy joke-ish taglines to accompany them. You're going to be going through Atlantis, Doom's Castle, all of Asgard, Mandarin's fortress, Stark Tower, The Inhuman's base on the dark side of the moon, Dr. Strange's Manor, Mephisto's Realm, and the Skrull Homeworld to name a few. As the guys on 2 Guys Buying Comics said, it's like a sight-seeing tour of the Marvel Universe. It's really amazing. And not only do you go through the areas of the Marvel U, you also encounter all
the accompanying characters that go with the territory. There are so many minor-boss fights and Major boss fights in this game, you'll have an geek seizure. I'm sure you've all heard the specs by now, but there are around 140 Marvel Character you can encounter in this game. That's mind-blowing. The guys at Activision really did their homework. I've always been a Marvel boy, but they were pulling out characters that I had no idea even existed. And on top of this, the character dialogue the used was just slathered with cheesy comic book dialogue, just icing on the "Living Your Comic Book Dream" cake. All in all, this game was awesome, and I can't wait to re-experience it on the Wii, whenever I manage to get my hands on one. If your on the fence between this and Justice League Heroes (which i find to be quite crappy), you should just go ahead and slap yourself in the face. Marvel Ultimate Alliance is the best comic-book game ever made, by far. It's just full of what you know and love, there's no way you can loose. Go out and buy it now. You won't be disappointed.
