It's true the games, the later ones especially had a very gritty, yet at the same time, very refined feel to them. And everything about the NEXT parts to the weaponry all had that very nice and solid Sci-Fi element. All the energy weapons and kinetic weapons made you really think that this is the way technology could go.

The look and visual feel of the NEXT parts also made it feel real.

Translating that to an RP setting might be abit of a trip, but doesn't mean it won't be fun.
