The comparison between the two is like comparing a ferrari to a dump truck. They both can carry passengers but one gets there a hell of allot faster with less cost per gallon.

I disagree. The whole point of having planets is so you can use it as a offensive and defensive weapon. I personally would say if you can keep a planet intact for let's say 30 some days in a standard edit then you should deserve to be able to use it as a weapon. If your in a unlimited game and there is 10k grid your afraid of hitting a fighter then go onto another game. It's unfair to those who take the time to build a mass amount of planets not to be able to use them. Sure they are a great defense but if those who attack you can't get through your defense shouldn't you be allowed to use them as a offensive. Also, if you are being invaded and you want to take DAYS to move a planet or face possible mass destruction of a planet evaporating then what is the point of having twarpable planets if you can't move them to a different sector for saftey?

I think there's a broader question about whether planets should have their movement delay configurable per-planet as well. Whichever we do, I think it should be consistent. So move delay and tpw would both be either game-wide or per-planet. Currently, the optional move delay is for all planets, not per-planet, so that might need to change. I could add a "planet-defined" setting to the planet move delay setting in the timings editor, then add a move delay and a tpw setting to the Gold planet editor.

Another possibility would be to add another level to the citadel that would remove the delay. An "Upgraded Planetary TWarp Drive" that takes advantage of new tech, blah blah blah to offer faster travel from sector to sector...?

I am of the opinion that moving a planet should take Days, not Seconds. It would be nearly impossible to really move a planet, so there should also be a high probability that the planet gets destroyed during the process.
