I liked the way the player came across a dead body on the beach, and looting the body resulted in a quest. The area seemed lively enough for a starting hub, and the voice acting was done well. The combat looked very fluid, and the death system is a very welcome addition to the MMO genre, in my opinion. The phased exp and loot system looks like it will work really well to help with the grind of "kill 10 rats" missions as well, since really all you have to do is tag a mob someone else is attacking, and you'll get credit for the kill. It also helps solve the problem with people trying to help you kill a group of mobs without worrying about the typical "I had it under control" response they'd usually get, since judging from the video, you'll be thankful for the help of others, often.
The video was about 20 minutes of the start of the game, and since the leaker was too busy not really caring about actually playing the game, not alot of the game was shown, but it was enough to hype me up some more. And no, I will not reveal the source of the video, and neither should anyone else, since it is against the rules, of course.
