In my current game I colonised a quality-7 world fairly deep within my own borders. I normally use these as research-booster worlds.
However, the one in question has three large influence bonuses on it's tiles, which makes me think it would produce a pretty huge amount of influence if I wanted it to.
The question is, does influence affect things globally, or just around the local area. There aren't any enemy planets in the vicinity, so would having a super-influence-producing world deep within my own territory be of any benefit?
