UC2 was a good game but it's very far form perfect I whould give it an 8.5, maybe a 9 counting the multiplayer.... the prodution standards are on top level but I don't understand why the gameplay is considered so good....the platfrom parts are almost "on-rails", there is no air control or timing involved. (except maybe a couple of exceptions)
The action parts felt to me like a poor version of Gears Of War, with a lower variety of enemies and weapons, less precise controls and worse level design (in GeOW, when the games get more difficult it generally means more and stronger enemies, in UC2 it usually mean less covers, not to mention that in UC2, when you arrive in a new area, often you die the 1st time because you don't know where enemies are coming from, that's something that never happens on GeOW).
