Only a couple of days until the next one is out now! Very much looking forward to it.
Someone commented earlier that the multiplayer wasn't great (on Brotherhood). the only problem I had with it was that not enough people seemed to play so it would take ages to get a game. As for the play itself, because it is so different to any other game out there I really liked it and the games I did play were fantastic fun.
Hopefully the mutliplayer in the next one will be similar and more people will choose to play it! (though I won't be touching that until single player is completed)
