My only issue with these rules is that they are a bit inflexible but yeah, things like this need to be straightened out. One issue is that not every FTL travel method works by "jumps". Think of the Warp Drive from Star Trek, for example. It propels the ship in real space on a constant rate and the sensors/crew can observe their surroundings or make course changes the whole time. Obviously, the most common limiting factor of these to be slower in comparison. This is no universal rule but dramaturgy wise you can more easily get away with making these "warp engines" slower than you do for jump drives. Warp-like FTL methods have several differences, including new sets of "ups" and "downs" for its mechanism. [b]Advantages:[/b] - Activating the "warp drive" is almost negligible in energy cost and, at least when nothing else is in demand, it can be maintained almost idefinitely - Warp travel steers the vehicle in realspace which means the crew is aware of their surroundings and can make course corrections the whole time [b]Disadvantages:[/b] - It may be slower (less physics-dodgy method than jump drives and as I said writers can get away with slow warp drives much easier) - Navigating in realspace means you still need to avoid larger debris and other hazards in your way - While you can react and make course corrections, at FTL speeds any "turns" you make would usually require tons of space since all those tiny delays in time add up - Warp engines don't make you disappear from realspace, you only became faster so the enemy may keep targeting you [b]Warp Drive applications:[/b] - Ships: see above - Missiles: the warhead travels at FTL speeds practically the whole time so it lacks the weaknesses of the "jumpdrive missile". On the other hand it's in realspace and has all the issues described above. - Other weapons: You can use something akin to a "warp accelerator" to propel projectiles or even energy beams at superluminal speeds for extended range and perhaps accuracy. - Communications: you can enhance radiowaves and such to travel faster than light, the so-called subspace comms in Star Trek are like this. Potentially inferior to jumpdrive-derived methods, tho. - Sensors: You can practically use the same tech to get FTL sensors which will be essential for this NRP anyways. Besides without FTL sensors you would fail to even navigate with a warp drive. - Computing, electronics: FTL circuits can increase the speed of computers and every electronic system in general. There are perhaps more but these are the most obvious ones. Note, you can also get various interesting applications for jump drives but in some areas they're more limited. For example it's rather difficult to imagine the application of jump drives for sensor technology.
