Unfortunately, as with many other tech sites, we have never really focused on game reviews in terms of gameplay - Hardware performance in games is another story, but we attempt to cover that ourselves.
Gameplay reviews would be more appropriately suited in our roundups if we were to focus more on games than hardware, or a combination thereof, such as neoseeker. Unfortunately as it stands there isn't the interest or the resources to do so.
That said, please keep letting us know, in the members review section, your reviews of game releases. I know personally, I don't often have time to keep up with all the new titles and what to expect from them so it gives me some good feedback on what to watch out for and whats good and crummy.
