1m = 128 quants

the two resons are the texture resolution and the units. Ingame i need to be able to show things with at least the size of 1 to 2 cm correctly. Since the lowest usable unit in gs is 1quant (if 1m=128quant => 1cm=1.28 quants) i stick to 2 quants to represent 1 cm.

so its basicly about the game your are making. The more detailed the scene has to be (ego games aso) the more quants your meter has. If on the other hand you make a space fight game or an invaders clone, one meter can as well represent 16quants.

but since models replace more and more the scenery, the quants get less important.
