Exactly! For example, I may think Starcraft was a game inspired by the Gods themselves, but it still is by no means perfect. For a reviewer to use the entire scale it would have to use a lot of ifs. GTA4 could've been a 10/10 if you like sandbox games, if you were OK with the gritty realism, if you didn't find the excessive violence offensive, if you are a fan of the series, etc etc.AlphaWolf13 said:Unfortunately if you were to knock down points for flaws, there wouldn't be games that actually get a... 10/10...
I don't like GTA4. Personally, I'd give it a 4/10 but if pressed to be neutral as much as possible, I would give it a 7/10 maximum.
Thus backing up what everyone else already said here. Numerical scores are just developer/publisher wank to keep the monies rolling in. Only reading the actual review you can get a good picture of what the game is like, but even then you might want to check more than one site since reviews can be extremely subjective.
