For one thing Wii games come out cheaper. If you plan on getting it day one it could be a factor to consider.
not really, I have all three consoles and will be getting it for an hd system day one, with the other hd system a month or so later.
But then again I do work for a living, having no children/dependants, am renting and have a lot of disposable income that I like to waste so I can appreciate that my situation is different from a others, how much cheaper are we taking here, £5?
The PC version is by far the cheapest at £14 byt I doubt many will be paying for it. (assuming people that play pc games just pirate everything.)
