Q: What's with these green, yellow, and red colors?
A: Assuming you are looking at our website and not at your Christmas tree, it's fairly simple: "good" METASCORES are coded in green; "average" METASCORES are yellow, and "bad" METASCORES are red. (This same color coding is also used for the individual critic and user grades.) If the numbers are too complicated to read, you can simply look at the pretty colors to tell what the reviews said.
Here's how the scores break down:
General Meaning of Score Movies, TV & Music Games
Universal Acclaim 81 - 100 90 - 100
Generally Favorable Reviews 61 - 80 75 - 89
Mixed or Average Reviews 40 - 60 50 - 74
Generally Unfavorable Reviews 20 - 39 20 - 49
Overwhelming Dislike 0 - 19 0 - 19
Strano che per i giochi usino un sistema diverso, eh. //content.invisioncic.com/a283374/emoticons/emoticons_dent1005.gif
