At the expense for suggesting a Trek like feature (I am not a huge fan myself) I do like the idea of perhaps adding a sub-category to the sensor research tree...cloaking or stealth ability. I think it would be great to add a cloaking ability that would hide a ship from other ships sensors UNLESS the other ship either reached a certain sensor ability or researched cloaking also. I can see some real stratagy involved in having one ship in a fleet without cloaking and 5 others that do. You could use that to suck the enemy in or in retrospect, be sucked into a fight you otherwise would not have chosen. The question is would the AI be able to use this type of item and stratagy, I think it could.
I would not want to presume this is something the devs could add so my question is, can you add something like this to the research tree yourself? If so, I would love to either try it or see it come down the pike in a future mod. Thoughts?
