Matchmaking on the 360 has always been great, the pc version works the very same
As ive said over on boards who needs dedicated servers tbh?
Maybe the uber competitive guys but apart from them [they are a tiny minority tbh] matchmaking works a treat.
Im off to Liverpol in a few days ill pick up pc MW2 when i get back.
Meantime im loving it on the 360, surprising how playable it is once i got used to the pad all over again.
Some guys on it would give the best mouse users a run for their money.
Im managing 20-40 kills in a 10 -15 min map which is more than enjoyable
