If you don’t feel like wading through reviews and just want a quick score to see if a game is worth playing, Metacritic is for you. It’s not a review website in itself, but instead aggregates scores from various game review websites.
Search for a game, and you’ll see a weighted score from 1-100. You can click through to read individual reviews or compare what the critics thought to user reviews.
A lot of the time, it’s hard to sum up a game’s quality in a single number. Thus, many people have issues with the weight placed on Metacritic, but it’s a fine place to start your research on a game. Just remember that a score isn’t everything.
