Well I thought about that. I don't have an Xbox but don't the games say Xbox somewhere on the front cover?
I guess I'm wondering if the review page shouldn't state clearly what system the game is being reviewed for? For instance:
here's the Armored Core: Nine Breaker review. If I'm sent the link by someone I can't tell what system this is for unless I know it already or it is mentioned in the body of the review itself.
Maybe at the top where it says "Review" before the game name it could say PS2 Review or Xbox Review?
