After watching the footage. It wasn't a remake but a reskin. Animations and sound effects were all the same. You can press a button to change back to the N64 visuals instantly. Still, it looked like a nice visual update. Funny how 3 years later Nintendo at E3 announced Goldeneye Remake on Wii with DG as Bond. Nintendo was dicks to do this but at the same time, they really should have bought Rare or at least found a way to keep the IPs. Be in better hands.
Rare wanted out from Nintendo especally after Nintendo started cutting Rare's funding.
The issue is too much damage was done that when Rare moved to another owner, the company was a shell of its former self.
