MMM lets see...where to start.....
1. Do you play on a HD tv? I only ask this because I'm a graphics whore and would easily pick the PS3 version over the other two if you are playing on a HDTV.
2. How important is online play? I would instantly say to buy the 360 version because it has far better online then any other console right now but if you ruled out the 360 (take another look at it
) I'd go with ethier the Wii or PS3 version. Both have online and I would assume the PS3's online would be a little better (not sure about the PS3's online since I don't own one)
3. Do you care about wireless? I'm not 100% sure if the Wii's is wireless or not but the PS3's is and the PS2's isn't.
4. Do you seriously want a PS3? I'm only saying this because a friend of mine bought a PS3 for lair and well...we all know how that turned out. Not to mention the big price tag. That leads to our next question.
5. Is money a factor? If you plan on getting a Wii then the Wii version would be the best because you wouldn't be buying a PS3 also. Even tho the PS2's version is cheap I wouldn't get it, no online and you will probably end up with a new console soon.
There are a ton of other questions you can ask yourself. My first choice would be the 360 version (think about it
) but since that is out of the question I'd probably go with the Wii version, then the PS3, and finally the PS2 version.
