IMNSHO you would be better off looking at a selection of reviews than an average score. Different reviewers or sites may tend to grade more easily or harshly than others, and within each review they may weight different categories differently than you would. Eurogamer, for example, gave the game a 6/10, but the review itself was generally positive. I've seen other games given low scores for not having cutting edge graphics (which I don't care about) or for not having multi-player support (which could be nice to have, but again I don't really care about), etc.
I'm planning on getting it come Jan 5th...
