To be honest, D&D rules generally do not mix with SciFi. The reason for this is HP bloat. One can accept that a guy in full plate runs through an arrow shower to start hitting people with his sword. But the same guy doing the same in a modern or sci fi setting? No.
Yet the D&D system puts a huge emphasis on melee and very close range combat. The rules are simply not made for long range combat where both sides trade ranged attacks and instead are geared towards bringing to combat into melee range. Yet this long range exchange is exactly how most SciFi combat would play out.
Eh, it's an abstraction. It doesnt make any more sense in fantasy.
and DnD, or a close equivalent, rules work fine for Star Wars, alternity, d20 modern/future, etc.
