Okey I have RA3. It is like this: Take RA2, update the graphics, add the land of the rising sun, make the cutscenes extremely funny and add some hot babes and add some more micro management techniques.
At first you think "Errrrrr EA games, another reskinned sequal". Then you fire up to LAN RA2 and "Hey... where was this option in RA2 its-... oh wait no it's not there. Damn where the other comma-... oh wait f*ck." And then you realise that RA3 is exactly like RA2 but waaaaaaaaay better.
If you liked RA2 then you will love RA3
Shitty side note: DRM 5 installs. Uninstaller released so you can get back your installs. You need internet for activation and if you happen to somehow run out of installs then you need to call EA, tell them why you installed it 5 times (do a little social enginereing noooooooooooo prrrrrooooooooobleeeeem) and they reset the counter for you. Somewhere in the future EA will release an official DRM-less patch/crack. The good part about the DRM though is that you do not require the freaking disc everytime you want to play.
PS: C&C3 is better IMHO
