i have an idea for the sensors, in the game, that coulde make it a bit more of a tactic in the fog of war.
What if sensor coulde send out vision Waves, on the conditon they have to stay in one hex and not move.
lets say commen ships With one sensor have smaller vison range and if specialised ship With a lot of sensors on it, the ship can stand still while they can send out vison Waves every 4 turn.
(you coulde station Your ship in a hex and send out Waves every 4 turn but if you move that vision wave is lost, also this shoulde not be a.
(move then gain vision and repeat the same pattern, it woulde not be that fun and it shoulde be more a loss and gain thing)
(it helps if the Tech tree coulde affect this too)
so that you can reveal the fog of war at great distance, (Without constant vision) but it will allowe you to gain the information you need (planets location, enemy location,spying. (without it being op)
Also a there shoulde be a distance between the ship, so they do not constantly have vision, X the amount of vison Waves sendt out in one area.
