Never winter to me is a poorly made diablo 3, and I didn't really care much for diablo 3. I don't see the wow comparisons at all I think that has just become a phrase to regurgitate when you find a game to be non innovative, standard fare. I didn't care about any of the chars didn't read any of the quests just followed the glitter line and spammed the attack hotkeys (to be fair there is some strategy later into the game when you get a full complement of abilities). The combat can be fun for a little while but becomes very repetitive.
The depth of char creation doesn't compare to DDO. Even the visual char customization is better in DDO, minus the ugly half elves of course :-)
Overall the game just feels unpolished and smells of a cash grab on the popularity of the never winter name.
