I love MAG, and i will be buying it for sure! I think its too bad its a 1st person shooter, but well.. making this game a 3rd person wouldnt be reliable.. it is going to be busy and 3rd person shooters are more tactical. Not that im saying you dont need tactics in 1st person shooters. :P
I think it's sad that there won't be an open Beta in Europe, i really wanted to play it.
