When I'm feeling down and I need a good laugh, I log into Metacritic. It's my favorite humor site!

I use it as an average of what critics. Usually, anything below 70 is not that good

Were're not in 1985, but in 2015.

You have official trailers/vidéos/infos  /etc, it's more than enough to see if you will like a game or not, without any review.

i just use metacritic to see user reviews and press reviews it might help on buying me a few old games but if it is a new one and I'm interested already in it, due to the trailers with gameplay, etc... then I don't normally use metacritic.

In 1985 you were less likely to see a CGi offical trailer of not gameplay to be honest. You might have seen a cringe worthy video of a 40 year old dressed as a teen saying a game is radical... but that's another story.

I use it as an example of the flawed review system. That's about it.

Under 80 - wont buy, wont even bother looking in to the game. It's all varying degrees of shovelware.

80-85 - OK, I MIGHT read a few reviews to see if it's of interest if its a genre I'm in to. Will probably torrent games of interest and then buy ones I think are worth having.
86-90 - Will read reviews and info about these games. Will probably torrent games of interest and then buy ones I think are worth having.
91-95- if its a genre I'm interested in will most likely buy
95+ - guaranteed buy

I find it nearly pointless. The games that get higher ratings are games that are generally heavily commercial, and are scored based on a checklist of commercial standards, and that never includes actual fun or interest factor, which to me are the two most important things.

I use Metacritic?

Jokes aside, I sometimes check Metacritic when I want to get a rough idea about something. It's not perfect but if a game's metascore is less than 50, it's probably rubbish. And if it's good, I should probably look more into the game. Other than that, I don't really see much use for it. Scores aren't very reliable because they're subjective.

I use it one way. If the game is like 60 or lower. I don't even bother looking at it anymore. The rest, I will look at videos and articles. Then decide to purchase it from that. I use it to filter the shit games.
