Must be old school but playing against unpainted figures does not do it for me. The whole point of the hobby for me is the visual impact and the game.
So how many points of each army do you have and play with and what portion is painted. I have unpainted units but they will never see the table unless they are painted and based.
Imperial guard 2000 points painted
Space Marines vanilla 2000 points painted
Nids 200 points painted
Orks 0 points painted
