played a bit of L2 beta. nice eye candy, very stable even in beta form, not harsh on the system (no system side lag), but a few things will keep me from buying it.
1. the control system. sorry, but id much rather use the keyboard to move around instead of Diablo style click and point movement
2. griefers galor already in beta. sorry, but thats why i dont play on bnet any more. to many children.
the overall concept is great, the game play (besides the movement and some of the UI) are great. nice quests. good char building system so far as customizing.
so yeah if you can overcome the 2 reasons above its a great game, just not for me atm.
