Modern Warfare 2 will be very familiar for those who played the original Modern Warfare...and that's because the game hasn't moved on much, and, in fact, gotten worse...
The first person story game is okay, I'll play it once...but the on-line multi-player experience is terrible.
Gone are the dedicated servers, the quick game joins, the glorious 40 player games, the occasional cheat (because the server admin kicked him and his winging mate...
All replaced with peer to peer hosting (read: laggy), automatic (read: poor) player matching, the maximum 18 player (9v9) games, and the occasional honest player, who, like you, has stumbled into a bot v. bot battle of the cheat...
I am now praying to the God of Honest Players that a dedicated server will be released, along with stronger anti-cheat measures, so that this emptiness I feel will go away....
But they have my money now...I don't think I'll ever feel as if it wasn't conned out of my pocket...
