Metacritic user scores are IMO invalid as measurement of the quality of the game, 99% of user reviews are either 10/10 great or 1/10 crap with very few in between. Also there is no way to check if the user has actualy played the game and for how long. Uncharted 4 is a PS4 exclusive and a big release and that means that for some reasons haters will give it low scores while they never even have played it, and ofcourse some legit don't like the game, and thus give it a 1/10 because with gamers there usualy is no middleground, and often, no common sense. Doom is multiplatform, published by the current most populair publisher Bethesda so I gues less childish behaviour there. It is sad really, no wonder that nongamers think so lowly of gamers considering this behaviour. But for information purpose just read or watch a couple of reviews instead of going to Metacritic, its irrelevent anyway.
