As far as I know they plan on putting FF13 for both the 360 and the PS3, but I believe FF13 Versus will only be available on PS3.
FFXIII: Versus will be for both Xbox 360 and PS3, but FFXIII is only for PS3.
And LOTR: Conquest is awesome- I have it for my PS3 and I love it Is that for Xbox 360?
Erm, and LOTR: BFMEII is a good RTS, IMO. Has a great Risk-like game with instant RTS immersion coupled in, in addition to two great campaigns and a world builder (and ROTWK has an even better campaign, IMO). I have it for my computer. I haven't bought a console for my 360, PS3, or Wii in a while, though.
Note: By "mine", I mean that the 360 is my little brother's, the Wii is my parents', and the PS3 is mine. But that doesn't really matter, lol.
It doesn't have wireless?...
Yeah, you need an adapter for wireless on the Xbox 360. I forget how much it costs, I got mine a while ago and never used it. The Wii and PS3 are both wireless, though.
