There were so many competing experiences in the seventh generation that it made sense to have a 360, Wii and PS3. But Wii and one of those other two in particular was an awesome combo. You could get the majority of third-party games that gen whether you had a PS3 or 360 and you could play Nintendo games and any third-party games that interested you on Wii.

I think I remember from back then that there was a time when a Wii and an Xbox 360 together cost less than a PS3.
