John:
I did the same thing in my tank game. I didn't mean to imply that you should always fit everyhting to a scale of 1 unit = 1 meter. In a realistic game, that is a good scale to use. In a tile based game though... one might want 1 unit equal to equal some other distance. If I was making a tile based RTS, then 1 unit = one meter would be too small if you wanted the tiles to be 1 unit on a side, which I think is a good scale for that sort of game. In that case, 1 unit might be 10 meters. Or 100.
