Probably not even 7 or 8 more 100s, it just went from 88 to 89, it's nowhere near close to climb to 90, considering the amount of reviews it already have (101 currently), any is only responsible for a bit less than 1% of the total score, and with it being a 89, a 100 would bump it just 11 points, which divided for 101+ (102, 103, 104... etc with every new review posted) amounts for only around 0,1 on the total score, so let's say it reached 88,5 or 89 (whatever MC considers enough to bump a score a point up), it would need around 9 to 10 more 100s, and only 100s, to climb to 89,5 or 90.

That said, they do weight their scores differently, so the math may not be perfect, but all of the major reviewers already posted theirs and I don't think any new review can have a major weight on the score anymore.

Honestly it looks much better than Uncharted did, back in the day.

Uncharted evolved a lot, it had plenty of room for that, Horizon already feels like Uncharted 2, IMO, I can't see it having any kind of major update like Uncharted had from 1 to 2, Horizon already feels like a very polished and accomplished game, to me, but I'll confirm it as soon as I'm able to play it.

By the way, Uncharted 88 is actually ahead of my personal score, but pretty close (mine being a 8.5), and as of now, Horizon seems much, much above of a 89, pretty much like Demon's/Dark Souls were.

POSSIBLE SPOILERS, I DON'T THINK IT IS, BUT YOU ARE WARNED 'CAUSE I KNOW YOU XD
I saw a guy hacking aligators and t-rex and putting them to fight their equals, and ffs, what an amazing thing, it was just incredibly fun to watch xD

I never expected to really like this game...and I love it. The combat is just so good, you feel challenged and empowered and everything is so fluid.  The enemy AI is really impressive and it is just georgeous.  I almost never take screenshots, but after I came across a Thunderjaw and tried my luck (which took a long time to take down) I couldn't help but show off.

One of the biggest surprises for me in gaming of the past ten years. Well done GG and Sony.

Or walking into you "playing" with Nier's 2B.

You could say that Horizon has been robbed of a 95 on Metacritic right?

I don't get worked up about critics, all I will say is I'd suggest it to everyone to try this game.  I really hope it sells millions and becomes a huge success story for Sony as admire them taking a chance and it turning out so well.
