As of this writting...

That's some rating system there.

And I'm sure at some future point the link posted above will not reflect the percentage rating shown due to future reviews/corrections.

EDIT:  Found the culprit:

ImpulsiveGamer is IMPULSIVE!

lol kojima hacked the site and put this on number 1 xD

Massively massively overrated game, even at 95% it's overrated and I don't think critics and fans alike will realise till a year or 2 down the line. Don't get me wrong it is a good game but it has many cons which other games from smaller studios and less popular developers would of gotten roasted for.
In my opinion 85% is a perfect score for this game which is obviously a really good score.

And there's still 5 PS4 games ahead of it!

Great programming. No input validation at all. SQL injection here I come!

I blame Wolbachia.

More impressive is there's more than 200 games ahead of it, too.

What have I been doing with my gaming time?

Wow what the hell are these people; GameSpot? It should have at least a 250%!!
