Rare returning to glory to me would mean that they would match the best of what they accomplished on the N64, since I didn't like anything they did on the 360. So with that in mind, there would be no Diddy Kong Racing, shooters have evolved way beyond Goldeneye, Perfect Dark was overrated, I've never cared for Killer Instinct, and I thought Jet Force Gemini was terrible.
So basically, it comes down to Banjo, Blast Corps and Conker completely kicking ass like they did on the N64, and even then, is it enough to sway me away from Uncharted 4, a new God of War, and PS4's superior tech? Not to mention that I like PS4's controller better.
Sony certainly doesn't have a huge stable of AAA frachises either (my opinion), but it would still take more than just Rare's efforts on the XB1 to make me favor Microsoft's console.
