Guh, so weapons are easy enough to replace, I've been replacing positron beams with gamma lasers which are still plenty fun. The railguns don't need much changing, just a little tweaking to power them with good old fashioned electromagnets instead of sophisticated gravitics. Missiles are missiles, don't need any changing.

Power generation can be a matter-antimatter reaction or miniaturized fusion, don't really care, I'll decide on it later.

Where I'm having trouble is the drive technology. My ships all have these giant engines, now what are they...

Any suggestions?


[@Hael] Or anybody.
