32-bit colors take up a load of memory, and aren't much different from 16-bit colors. However, the current generation of games is in a current era of 16-bit colored games, with a few higher, here and there. Whatever the case, there should be an option for changing between these things. As far as I know, the jump from 256 colors and 8 bit (65,536 colors) is the largest. 16-bit (16,777,216 colors) is pretty sufficient for good graphics. ;-P



In any case, the game, if it is released, should not take any steps back, or stay in the same place, in any category.
