lets not forget... They have completely screwed us over.. Many countries arent even getting dedicated servers... so screw em and lets pirate the SP!!!:Dbut.. there are some that managed to hack the main system and make official dedicated servers XD and they even allow cheats on them:Dhahahahaha so there are going to be all these high ranked ppl soon... and also.. Many People with Modified Xbox 360's have been banned... Microsoft sent out something that checked valid chips, etc. so all those with customized machines cant play MW2... hmm... :/ they have realled done it this time... COD4 was one of the biggest successes but now they just shot themselves in the foot and ruined an awesome game for many...
Well, I don't play any FPS in multiplayer, so I don't either plan to play this one.
But, to comment SP, I love it, great interesting missions, graphics amazing, sometimes I fell like I am really there, weapons are awesome. Those stealth missions are my favorite, just enjoy sniping around. :)
Tried it out at a friends, and I've got to say that it's a pretty good game. If I get it, I'll probably be getting it for the PS3, so I am really not affected at all by any modifications made to the PC version. In all honesty, if you're getting it for a console, it'd probably be a good purchase.
