This kind of stuff REALLY needs to be documented. I ruined a whole game building influence starbases, and only after putting several modules on each, discovering they weren't doing anything.
3 games later, I still do not really know where to position influence starbases relative to my own colonies, the other race's colonies, and the various borders, etc. I sort of understand how influence works, but I do not understand how starbases affect influence.
I really hate being forced to GUESS what things do in a strategy game. In order to plan a strategy, you need to understand how all the basic game mechanics and technologies work. The fun is in APPLYING them and adapting them to your needs, not trying to figure out what they do. Without understanding how things work and what they do, it's as much a guessing game as it is a strategy game - and I find that frustrating.
