As far as Warmachines is concerned, I really like Khador. Their story is awesome and I dig Russian-esque nations. Plus they essentially have Baba Yaga as a warcaster. On the Hordes side of things I'm partial to the noble Trollsblood and the Blindwater Congregation, a pact (lesser faction), of voodoo alligator men.
Here's a little taste of the artwork for the games (which is phenomenal).
|Trollbloods, powerful , honorable, displaced warriors|
|A lurk and a gatorman, two of the monstrous races you can play as in Unleashed.|
|Definitely not Baba Yaga and her hut...|
|War forces of Cygnar, the crown jewel the Iron Kingdoms|
