Digital video game store Steam added a user reviews feature today. So, like iTunes or Amazon, you can read (and write) reviews for a host of PC games.
The review system should look familiar to anyone who's shopped online before. At the bottom of any game's page, you see the reviews rated "most helpful", and you can click a link to read more. You can mark good reviews as helpful and ignore the rest. If you've bought and played a game on Steam, you can leave a review yourself.
It's a simple review system, but one that will probably be very helpful during your next video game shopping spree. Technically, the review system is in beta, but anyone can use it. Hit the link to read more.
