Hey folks,
i have some ideas for the future gameplay improvements which i would like to share you. I hope the developers reading this section 
Sensors
I think this section needs a bit rework. First, we need an anti sensor module which creates a blind spot what the sensors cant see ( only a super strenght late game sensors). This module is only buildable on military starbases and effect in this range (3-4x radius). And the other thing is here, the sensors should not allow sight in and behind the nebulas! This two thing is extremly important tactical improvements in my opinion, you can hide fleets ect.
TLDR;
- new sensor jamming module for military starbases
- sensors cant see in and behind nebulas!
- new sensor which allows you to see trough the jammed areas and nebulas (military starbase module)
Diplomatic
The AI has already been improved in some ways, which is cool, but i found a very specific area when he just cant catch up. They didnt make any Alliance. In my past games, i could switch the tie easly because i use to manipulate the AI, i just make a non agression pact witch one of my strong neighbor and then strarted picking one by one the weakest. When only a few left i make ally with the one i made a non-agression pact before and then smash the other. The AI must use the diplomatic battleground too, make alliances againts the most threatening opponents, in this case: me.
TLDR;
- Make the AI more diplomatic power, create alliances, pacts, war together ect.
I played most of my games on gifted difficulty if its means something.
So thats my toughts for some tactical improvements for the game, it would be cool for singleplayer and even better for multiplayer.
