Real Time Strategy is something of an enigma when it comes to running on a console. The games industry has tried in the past with some success with Lord of The Rings, but it's not until now that I feel they have managed to make their mark on the console market.
C&C has already been released on the PC and in many ways this version is identical. The major differences are :-
1) Controls are by the joypad. This is very intuitive and quicker in some aspects to the mouse\keyboard combination. Micro - Mangement is a bit hard as selecting a single unit can be difficult. Overall the joypad performs admirably on this title. I don't think mouse\keyboard purists will be converted and some people may not get to grips as quickly as they liked but practice makes perfect.
2) Support for the XBox Live Vision Camera which allows you to all see eachother in real-time video. This adds a new and ultimately rewarding aspect to the game and makes it more interpersonal than the PC version.
3) Exclusive modes - Unique to the 360 the developers have added a few extra modes which will proably appear on the PC once they mod it.
As for the game....it's got a blockbuster presentation, compelling story and the gameplay is second to none. I really thought it would suck, but this game is the best RTS game you'll find on any console, and considering it's stepping into the PC arena it deserves alot of respect for that alone. Buy it, or at the very least download the demo. I would advise you read the PC reviews first to help you decide.
Pitty the PS3 didn't get this, they could have done with at least one good game this year ;-)
