I want to see these kind of things in the game:
It will be very interesting, if into the space (in to the zones) will be some kind of special objects, like - animated plasma effects, asteroids twister (moving asteroids fields), asteroids with tunnels and caves, small nebula (like it was in the X2), ancient alien ruins, debris, ...
Here is example
video trailer, I was created few kind of these special objects (without special abilities, of course) into the my mod for X2.
Also will be much more interesting, if special objects (small nebula, plasma effects, ...) have special abilities, like - eating ships shield, hull, disable radar, weapons, slow down ships speed and other interesting abilities.
Then you will need to be careful to avoid these dangerous special object territories.
Player can use these dangerous special object territories in the battle, to escape or hide player ship from the enemies or even ensnare an enemy in the trap.
