First, nothing says MOON BASE does it - you know, interlinking connection tunnels, domes, that sort of thing. But maybe the ultimate test of mankind, living and fighting in a ZERO-G or airless barren rock environment is NOT where you want to take your Sci Fi battles - after all I see a lot of green out there in blogland.
Second, what happens after first dirtfall? How do you expand your prefab palace? Go up maybe?
I found this superb 3-D render by Roomper. You can imagine 2nd generation colonists breaking out from their portakabin environment - building outwards, with more levels and a city as we know it begins to emerge.
Maybe this is the home of the Mayor of Dirtville, son of a 3rd generation Colonist family. Or maybe it's part of the slums of a shiny city of tall iridescent spires. It has a very Blade Runner feel - don't you think? Wouldn't it be great to have a small district like this to game in - Blade Runner Ambush Alley style - rather than mono-level portakabins or ersatz Middle Eastern adobes?
