I want to experiment with a more close-range, beam-friendly, TV sci-fi type of thing. I figured the best way to do this would be to cut the speed of everything(missiles, ships, fighters, etc.) down to 20-25% of it's original, and cut tracking speed by 2/3 to 1/2, whilst keeping fuel usage the same. This would result in shorter missiles ranges, and more likely missile interceptions from beam point defense, especially since it's range hasn't decreased. However, there are problems with this. One, ships would need a ridiculous amount of fuel to get anywhere(which something like the hyper-drive might be able to fix, if reimplemented?); two, I have to question whether this would make missiles completely useless(or at least for their cost), which isn't the idea behind this; and three, how would I go about doing this in the first place?
