You've got to be joking.. You think selling Rare was the stupidest of all time??? What has Rare even made since leaving Nintendo?? Crappy Perfect Darks, Kameo.... Viva 'no sales' Pinata. It's been a failure for Rare and Microsoft, both in quality and success. The acquisition by Microsoft was an attempt at ruining one of Nintendo's biggest developers, and it failed, since Microsoft's console doesn't have the right audience for Rare's type of games. So really, it was a bad decision for Microsoft, but nonetheless no where near one of the worst in the industry's history.
The worst are the Dreamcast, N-Gage, Nintendo sticking to cartridges, Nintendo bringing out the Gamecube purple and shaped like a lunchbox, and $599 for Sony.
Though, really, the XBOX project is actually statistically the worst decision of all-time, as it has lost the most money of any console ever. Same goes for the 360.
