That being said, Nintendo acquired a huge share of Retro Studios around the same time. So the question is, would Nintendo have been better off investing that money in a major stakehold in Rare, or did Nintendo make the right decision going with Retro?

It's worth noting that Nintendo acquired Retro for the obscenely low price of $1 million, while Microsoft paid $375 million for Rare.
