It's a great episode and yet another i recommend viewing. I'm not alone in that opinion and here's a link to give you a better idea.
The monorail is a great idea as i previously said. Perhaps it can be a 10 tunnel stretch for each time you construct a piece and the drone boost that can be researched can solve that issue for you enabling aquick construct? A nice to have and also a possible way for connecting other bases you have established across Aven.
What I want is a governors residence and an upgrade ability for it to be able to do extra things. Maybe that will be coming with the extra landing platforms for the expenditionary ships or transporters?
Did you check out the new video and update material on the Gamasutra - Press Release that mothership mentioned a day ago?
