we refuse to have something like races in the game. Only diversity, when you completing your ship or base is manufacturer. Like today, there a lot of different approaches to the problem. For example national agencies like NASA, ESA, ROSkosmos, and private like SpaceX, Bigalow Aerospace, Orbital …..
Each manufacturer have own design and individual solution. This is what we trying to imitate.
When you completing the ship, You can have only one brand, or mix it with a lot of different manufacturers. Like today on ISS.
For the future we want players to have own manufacturers and create own designed modules in the open source community.
