LAG
But seriously... I love NW.. I love how you have fixed the game since launch.. but 14.7 and NW now make it nearly unplayable.. and no, its not my isp. (1 megabit connection ) and no its NOT my computer or vid card.. (Latest and greatest of course =p)
Please... do something..
I get to play 5 - 12 minutes at a time before server error crash.
