Being that our society is taught from a young age (via schooling) that average is somewhere in the 70% range (C's on the report card), it only makes sense that reviews follow the same criteria. A 5/10 game is, quite frankly, pretty awful, but that doesn't mean it got nothing right. It might still have a decent soundtrack, smooth controls, or some other beneficial quality.
Money can't buy happiness. Just video games, which make me happy.
