Wii, PS3 or XBOX 360?
And please keep in mind stuff like "Wii because it sold the most, that's a fact so 2+2 = 4 = 9000> 8000 - (-1x-1)xdffd3d && 2+- 4i" does not count. Sales numbers are one way to define it and if you want that that is fine but it does not make it automatically the winner by universal standards that are more important than the others. I think this is a very personal thing where you can decide to make it count by sales of consoles and/or games and/or hardware and/or exclusives. It does not have to be exactly this one element.
And before you wonder what this weird post is about, I just googled "who won the console war" so I wrote this as preparation.
And of course some people here lost the game because they went against the context of this thread. Good job.
