Game wise, Dave has spoken a bit further on how the law vs. criminal battles will work out for the game. Criminals will be able to battle against criminals, but enforcers will never find themselves matched against one another. This will open up the possibility of multiple front wars with other criminal factions, rather than a simple two front game.
Also, the game will feature large scale battles as well as "metagroups" where the game determines balancing for players who are doing exceptionally well. Dave's example was a group of 5 elite players might be matched against 15 normal ranking players, just to give the elite players a thrill and the 15 a chance against these 5.
