You know what i havent seen the game that could make it more interesting is randomly occouring natural wormholes that remain open for say 5 game turns. This could be a random event aspect ie temporary wormhole has opened to x system and our scientists expect it to remain open for x turns where it will naturally dissapate (could also happen to normal wormholes i know they close in this way as a random event) - like to see it happen a bit more often in the game also.
Or perhaps wormhole malfunction where a ship disappears when it goes through or ends up in a completley different system.

This might annoy players as they prepare for an invasion but could make the game way more interesting.
