It fails the Notability Creteria.
http://en.wikipedia.org/wiki/Wikipedia:Notability
Ive put a proposed deletion on it.
Don't get me wrong, I love GWx, but wiki just isn't the place for such a non-notable topic.
There are insufficient published works including but not limited to newspapers, books and e-books, magazines, television and radio documentaries, reports by government agencies, scientific journals, etc. about GWx
The Total war games have plenty of exposure in published works altho wiki's article on them lacks cultural and other refrances.
