this is not something hard, if Uncharted 4, sells 2 times more than Halo 5, already will be surpassing the "Biggest Line Up".

True but I think ND themselves is done with the series. From the way they talk anyways they seem to just be done doing this games. You could be right though.

The Last of Us, actually have potential to be a more sucessful series than Uncharted, the game sold like 10+ Millions with the game, and the Remaster.

Yes its the userbase. Please direct your attention to Black Ops 3 sales. Userbase matters. In order for an Xbox One game to compete with a PS4 game, it will need sky high attach rates.

Again, look at all the other Halo games that sold much better on a lower install base. Look at how Splatoon is selling better than Halo on an install base of 12 million. Install base is not a legitimate reason.

Userbase should be a non-factor when comparing an HD remake collection that many PS4 owners have already played to Microsoft's flagship exclusive title.

OK It looks like giving Halo to 434 was the wrong idea, as since then with their halo games the franchise has lost lots of players.
My Question, Which company should MS have given the Halo Franchise to?

So, despite all of the counter examples which demonstrate that in the past, the Halo series in particular has essentially been "userbase" proof, with previous numbered titles all selling at much higher rates often times with lower install bases, along with other games like Splatoon which has sold more than Halo 5 with an install base of 12 million, you're still going to chalk up the relatively poor sales of Halo 5 to install base?

And really? Black Ops 3 might not be the best example to use for install base considering that Black Ops 3 on PS4 and an install base of 36 million is currently outpacing the sales of Black Ops 2 on PS3 which at the time had an install base of about 75 million.  So there's that.

I think despite the obvious factors that made this possible that very few of us would have guessed that with all the factors that UCC would be more than Halo 5 is the real talking point.

Halo will always have some of my favourite moments in gaming even though I never owned an MS console so I am sad to see it decline as a brand

People are forgetting that just about all the sales came from a bundle. It was a standard PS4 bundle. As I said, it did 250k in the US for the whole year without them.

Both games were bundled. One bundle did so much better. It also had better normal sales.

It's open and shut. Uncharted has more brand awareness now.
