Depends on the game for me.
Flames of War and Command decision, definitely. battlestar Galactica and Stargate SG-1, definitely. Crockodile Games WARGODS OF AEGYPTUS, definitely.
If they can be improved, prepaintedI'm for it.
BTW....Memoir '44....yup, boardgame, but I personally also consider the miniatures fair game if they can be omproved to a players tastes. I seem to remember Brumbar44 over at the od days of Wonder Forum did some spectacular stuff.
If I could speak the language of rabbits, they would be in awe, and I would be their King. I would be kind to my rabbit subjects...
