Can't bring myself to play WH40K. As much as the lore intrigues me (and much as I loved Space Marine), spending that kind of money on miniatures just does not appeal to me.
That being said, I'd totally play Chaos if I got into it, specifically Khorne.
Khorne is a heretical god D: For fools and barbarians
My brother plays Tzeentch, all Thousands Sons.....They tear any marine army apart due o A,P.3 rounds.
I know xD my faveorite thing is still lucius and an Aspiring noise marine with a doomsiren in a rhino. they roll up to any spacemarine squad and slaughter it. and they're still pretty nasty if the rhino dies
