Radical Alternatives: How SHOULD Size and Speed/Range Affect Chance to Hit?

Should any of this affect how lighting penalties work? Whatever happened with all the lighting stuff? Did that get hammered out?

Realistically, bad light does a couple of things, none of which are terribly well represented as a simple skill penalty:

1. Scotopic vision is lower resolution than photopic vision, limiting peak accuracy. This is not all that directly relevant at short ranges (20:2,000 vision is adequate to hit a human sized target at 10 yards) but is a problem at longer ranges.
2. Scotopic vision has a lower frame rate than photopic vision. This is a problem for moving objects that are moving erratically or aren't present for very long.
3. The above effects, along with loss of color vision, make target identification much harder, increasing the odds that you fail to recognize a target, or think a non-target is actually a target.
