Alright with the coming advent of cloaking, I've come up with some ideas to help prevent abuse of this technology, in spite of OP putting in a "safeguard" of using energy crystals to limit it's usefulness.
This is merely a suggestion and some ideas to toss around, so take it for what you will. I dunno exactly if they are implementable in the FL engine, aside from cloaking.
Take note, all of these devices can be limited as the cloak in that it's power source will be fueled also by energy crystals.
ECM JAMMER MODULE - This electronic countermeasures suite allows a ship while still visible to the naked eye on screen, to become invisible to all NORMAL scanners with sufficent energy crystal fuel for as long as it lasts.
ECM ACTIVE PROBE - This electronic countermeasures suite allows a ship to detect any ship regardless if they are using a ECM JAMMER MODULE, for as long as the ship's energy crystal fuel lasts.
CLOAKING MODULE - This electronic countermeasures suite allows a ship while still visible on scanners, become impossible to see with the naked eye on screen, for as long as the ship's energy crystal fuel lasts.
DE-CLOAK PROBE - This electronic countermeasures suite allows a ship to see any cloaked ship for as long as the ship's energy crystal fuel lasts.
Hopefully these electronics suites can all be "stacked" and used simultaneously however, they will expend energy crystal fuel rapidly when done so as each module consumes a certain rate of energy crystals.
So is it possible?
Sound like an idea?
Throw it in the trash can Ryleous? *facepalm*
Anyway, let me know what you guys think.
