Open world. Based on the news, I very doubt this would happen. But here's what I'd like to see: There apparently is some "behind the scenes" matchmaking, that matches friendly people with friendly. I want an option to be a "outlaw" or "renegade" or something. While being one, instead of matching with friendly people, you'd be able to kill those you find. To make it fair, the players might get a warning like 'Warning: there are reports of an outlaw in the area" So, for example, Bob and Jill are doing a quest in the Plains of Daraj. All of a sudden, the warning appears, indicating there is danger. If Bob and Jill kill the outlaw, they might get some money from a bounty, or maybe experience or something. If the Outlaw kills Bob and Jill, he might be able to take items from them (probably not) or just experience. I'd make the game alot more interesting.
