I tried the demo on my PC and on the PS3.
On the PC it was only possible to get into a game if you have a large friendslist or are in a social group to get invited.
On the PS3 its impossible to get into any game,it can't find any
When i was in a game its fun.
One thing is for sure the multiplayer matchmaking is an epic fail, i can't believe they did such a stupid stunt.
