Why did Nintendo dump Rare

[CapAmerica]

Nintendo was given the option to buy Rare and Nintendo laughed at them and sold them back their stock.

Rare was a Money pit, Nintendo dumped lot of money into them with very little return. It wasn't worth keeping them. Especially with most of the talent gone. The only games that brought in any money for Rare were Nintendo owned series and Nintendo could do those them selves.
