Hello im looking for a game and im not sure it exists yet ive looked alot

Here's what im looking for

1. Strategy/simulation
2. Space Theme
3. A semi active player base i dont want a dead game but it doesn't have to have 1000 people on at a time
4. Complex* this is key
5. A good amount of customization of individual ships no theres 10 ships thats it and u cant do anything about it. preferably they give you a ship hull and you add parts.
6. Complex battle system not the i have 10000 attack power and you only have 8000 i win crap.

Thats about it in short im looking for a moderately active complex game.

If anyone says Astro Empires or OGame you can go strait to hell
