because the people who make the Z.O.D. game line have started directly copying clan omnimechs.
(not sure if i can link to their sales site directly, but if you go to souldark.ru and check out their Z.O.D. section you'll find them)
like the "Great Wolf Death"
the "Dire Forest Felinid"
it has direct copies of the Dire Wolf, Timber Wolf, Mad Dog, Warhawk, Nova, and Viper. so far.
