I got a chance to play around with the online beta a little while ago. That was enough to turn me off from this game. I much more enjoy Call of Duty's multiplayer than this. MoH's feels like Bad Company's multiplayer, but without the good stuff (aka, destructible environments.) Just something about it, maybe it's the pace or feel of the game... I just didn't enjoy it.
I had hopes for the campaign to be good, but from what I hear it suffers from some problems as well. Something about nonexistent character development and problems with checkpoints. Explosions not looking like explosions. Either way, I'm still pretty interested in trying out the campaign at some point.
I think it's safe to say that this game seems to just be another run of the mill modern FPS. I believe they're planning on making more MoH games, so hopefully they do something that makes this series a bit more interesting and unique. As it stands, I'm much more excited for Black Ops.
