OMG my hardest decision ever! I get GI for free because I bought like 3 months of Xbox Live from GameStop. I love it. OXM is my type of magazine though because I only play 360. OXM also has demo discs that are awesome. This is not really a question I can answer.
Uh... GI, because they cover games that aren't for the 360.
He just told you not to post like that. That is considered spam.
OXM's is simply more funny, and interesting. I actually read almost every part because it's usually interisting. When reading GI I usually skip page after page after page after page after page.....until I find something worthy of my time. OXM also has the demo discs which usually help a lot when you can't decide if you should get a game or not. Also let's not forget the free gamer pics and themes!
