I have a simple base, but I don’t like it. It doesn’t look what real buildings look, as if someone have decided to put random objects around the building. I need to think about how space agency building would look, considering real-life stuff and tycoon genre of the game.
I tend to base my builds on real life structures I can find on Google Maps. Perhaps you can look around a city in Street View and find an office building that fits the theme of your base. If you want, you could remake a portion of the Kennedy Space Center in Florida. Like the Headquarters Building:
Like what the guy above me said, just go on google maps and look on street view for any references. That’s what most groups do except they also put down satellite images on the map so it can help them better with making it for size.
