I love the Zero Punctuation reviews, they are hillarious!
Read other reviews to hear some good then listen to his to hear the bad. You still won't have an absolute picture but you'll have a better clue as to how good the game is. I agree that you really need to wait untill actual end users have the game in hand and report on their experiences.
I found the same problem with a lot of hardware reviews (thank Beaver I found this site

) when I started looking into buying the parts for my first rig. According to the reviews I read the nvidia 650 boards were the 2nd coming and I almost went that route. Then I checked out some forums and ditched that idea fast.
A lot of reviews are nothing more than the slightly re-worded OEM press release IMO (not here). For games, beleave the gamers not the advertizers.
