I actually only clicked this thread because I thought by western MMOs you meant not Japanese.
Ha that's what I thought at first as well, then Iw as intrigued by the thought of a Western-themed game.
There are some good Western-themed games out there:
Call of Juarez,
GUN, and of course the classic side-scrolling shooter
Sunset Riders.I get the impression this Western MMO is based on some level of realism, kinda like
WolfQuest; which was pretty cool but had no depth and no sense of character development though it was educational. In all fairness it was advertised as a wildlife simulator anyway.
