The only way we could truly determine what Rare would have offered Nintendo is by looking what they offered the xbox, which, of course, is jack-friggin'-squat.
I don't get the argument. Rare would have added to Nintendo's lineup? Just like the last 3-4 games they made for Nintendo platforms, which were StarFox Adventures, DK64, Banjo-Tooie and Conker.
None of them earned Nintendo much in the way of sales, praise or recognition.
I think, Ian, that this is your natural desire to see everything which Nintendo does in a negative light which is interfering with your ability to note the painfully obvious. The painfully obvious being that Rare's work went downhill LONG before they were sold off like the dead weight that they are.
