Metacritic:
LoZ - 97 > Uncharted 4 - 96 > Halo 5 - 94

Sales:
Halo 5 - 10M. > Uncharted - 8M. > LoZ - 2.7M.

Completely agree with the OP.

Yep.

If Nathan Drake meets his end in Uncharted 4, then

Meta: Uncharted > LoZ > Halo

If not then like you said

Meta: LoZ > Uncharted > Halo


Sales: Uncharted > Halo > LoZ (By the beginning of next generation)

theres a rumour he will die!? say WHAT!????

I agree with the sales part. Though I think in terms of review scores it will be Uncharted 4 > Loz > Halo 5. This is since most of the time Nintendo games aren't as hyped ( review wise ) as much as Sony exclusives. 

 After further reasearch I now agree with the OP. Metacritic scores are amazing for all Zelda games.

Edit: Tried to use strikethrough text but it isn't working.

Zelda Wii U will sell less than U4 and Halo 5, will be the better game and will have the better single player gameplay value.

Halo 5 will sell more than U4 and Zelda and will have the better multiplayer gameplay value

uncharted 4 will sell more than zelda and less than halo, will have a better single player than halo, but will be the game with less gameplay value, because after you play 10 hours of a ND game, there's no real reason to play it again. great weekend experiences.

And that's the bottom line, cause stone cold said so.

Metacritic:
Uncharted4>LoZ>Halo5

Uncharted and LoZ could go either way, but ND is on a roll lately so if I had to bet I'd go with uncharted 4. 343i has yet to make a game that can even be put in the 90+ bracket so it's safe to count them out.

Sales:
Uncharted4>Halo5>LoZ

TLOU has brought a lot more fans to ND, and combined with the PS4's dominant position Uncharted 4 should beat out Halo 5.

I was with you until you said that! Outside of that, you're spot on!

sorry it's just my personal experience with their games. I like ND a lot but I never play the games again because the first time is enough, Uncharted 2 being the only exception.
