I usually go check out:
www.gamesarefun.com
www.insertcredit.com
www.gamestyle.net
For info about games before I decide to purchase. When I can be bothered to buy it, I usually check out Edge magazine too. I don't wholly rely on reviews to make the decision for me, but I like to get an idea of the problems with the game's design and those sites usually do the job. Naturally reviews are on person's opinion, so I use them as a guideline, along with people's opinions on forums too.
