You either love it or you hate it!
RA3 is your generic CnC game with the usual tactics of build your base, defend it a bit and send out an army to destroy your opponent. Engineers play an important role and as you would expect, there are loads of wacky units such as transforming heli's, amphibious battle ships and vacuum bombs to name but a few. This stays true to the RA3 formula and makes the gameplay exciting as some very odd things can happen. You have your commando units aswell.
Gameplay is not about rushing though as every unit is valuable, having a secondary attack. This involves a lot a micro-managment but this really adds diversity to your force which means you have to use clever strats to alter and confront a new situation. Gameplay is also added to by the serious focus on improving naval strats. It doesn't mean you have lost if you dont go to the water but it is handy if you do as there extra resources and some very powerful water units. So all those people who say CnC is basic and about rushing with no real strategy are wrong as there are many options to choose from.
The main love hate area is the graphics. They are a little cartoony which I don't mind but this can really get on some people's nerves. Water detail is very nice but his has high requirments to play on full graphics. With RA3 though, you can really tone it down meaning lower-end machines can still run it.
Single player is strong with good campaigns and as usual, very nice cutscenes that immerse you into the univverse. The women are very fit which gives geeks some cheap porn and multiplayer is very solid. Maps are quite good with a good range but I thik almost every map has a signifivant body of water which might annoy some people.
The only part i dislike is the uber-tongue in cheek humour. I know that is what RA is about but they have really pumped it into RA3 which kills the atmosphere slightly. I just try and ignore it and get on with the slaughtering of soviets and japs.
Overall, RA3 is a very solis RTS game that is definitley worth a look at for strategy fans and a must have for fans of the CnC series. People say EA have ruined the series. I think not.
