Summary: (8/10)
Marvel: Ultimate Alliance is a very good game. Most of the graphics are detailed and colorful. Great sound, including the voice acting. Lots of action, with each character having unique powers/abilities. A little puzzle-solving and a bunch of optional trivia questions.
But it's the great superhero/supervillian story that makes you want to keep playing.

Since the game was originally designed for consoles, using the keyboard and mouse to play took some getting used to. But, by the end of Act 1 (there are 5), I was fairly comfortable with it. After the Omega Base mission, I highly recommend using the Training Simulator to practice. At first you'll only be able to do it with Captain America, but as you find Simulator discs, you'll have more practice missions to go on. And they are no walk in the park. Besides racking up experience points and credits, you can get bonuses for your characters if you reach certain score levels.

Your characters \"level-up\" after gaining enough experience. This happens automatically, increasing health, energy, and melee attack damage, in differing amounts for the different characters. These characteristics can also be upgraded by certain pieces of equipment (only 1 per character), or by specific bonuses you find lying around, or by upgrading their uniforms by spending credits. Credits can also be used to upgrade their special powers, but normally you'll just use the skill points you get when they level-up.
(Special note for Wolverine: I don't think the game explains this well enough. Wolverine is different from the other characters in that he has 3 pairs of powers that switch, depending on his level of \"rage\". When he's below 100% rage, the first \"non-rage power\" of the pair is in effect; but when he's full of rage, then the second \"rage power\" replaces the first one (because it's nastier). So even though he only earns half as many skill points as the other characters, it's not a real disadvantage; because, when you upgrade the non-rage power of the pair, you're also upgrading the rage power at the same time.)
Also, during or after Act 1 (I don't remember), you gain access to the \"My Team\" function, which essentially allows you to choose bonuses for your entire team. The longer you play the game with the same set of characters, the more upgrades you can give the team.
A lot of characters, uniforms, and powers have to be \"unlocked\" by various means before you can use them. Although, after you play through the whole game once, all of the characters that were unlocked the first time stay unlocked, so that you can choose any 4 you want to start a new game with.

Now, why it's not a perfect 10 ...
The third-person camera angle: sometimes I wanted the camera angle to turn faster than it would; a number of times I wished it would zoom out farther than it allowed; and, usually, when an object is between you and your character, the object becomes mostly transparent so you can still see your character; but when that doesn't happen, it can be quite frustrating. I also hated the fixed camera angle that was used for most of the battle with Ymir.

The three other computer-controlled characters on your team don't always avoid the obvious hazards of the environment. There's one area in Mephisto's Realm where I still don't know for sure how they got killed. (Note: Even though the game does prevent you from just walking off the edge of a cliff, if you are in the air when something pushes you over the edge, you can fall to your death.)

For this PC version, there are atleast three boss battles where you have to suddenly stop using the mouse and use only the keyboard. Now, you might actually be better off using only the keyboard to play through the entire game, but nowhere is that suggested by the game.

I was also disappointed with the final battle. Two parts didn't make sense, considering the power that we were supposed to be up against.

Some minor things:
-Noone plays online. (doesn't bother me)
-Had to reinstall DirectX 9.0c.
-You can't save anytime you want to. A Portal allows you to save every 5 minutes, but it's not always available.

Overall, it is quite fun to play. The first time through, I just used the default team all the way. But now, I'm playing it again using the Fantastic 4. I'm already thinking of which characters I might use if I go for a third time.

Summary: I bought this PC game some weeks ago. What I want to recommend is the story, it is very attractive and I am enjoying in it. Besides, the graphics is awesome, which means you need to have good machine to play it. Some person concern the graphics. For me, I think the graphics is awesome. I am wondering whether some folks has good machine to play this game. When I play game, I like to play gae online with many people. But it seems no much people play online. That is the point I really dislike.
