Rise of the Tomb Raider - timed exclusive actually a big deal.

It's also coming to 360 so it in no way will compare to a fully next-gen Uncharted 4.
Even if it was XBO exclusive though, it can't compete with Uncharted. Just look up the sales of the newest Tomb Raider and Uncharted here on VgChartz. The remaster sold particularly bad on the XBO.
