Road map
Alter Universe is on an early stage, and ideas just keep coming.
Procedural Planets
Your planet is unique and will establish some characteristics of your civilization. It's not the same to launch a rocket from a super massive planet right? So you may have a bunch of resources but your neighbour could be already mastering space travel. This stage was about getting it right with the resources, atmosphere, size and natural satellites generators and also overall graphical appearance of the planets.
Building and Backend
Soon enough your small civilization will start to grow and you'll have to support it by building infrastructure. Create cities to provide living space, industries to generate the resources and food you need, research facilities, defenses, because there's one thing we know for sure and that's that you're not alone in this galaxy. This stage is about developing the interface and code for the building mechanics and the backend on the server to save and manage all the data you generate with your planet.
Mining and Exploration
It will come the time in which building in space will be more logical, for that you'll have to get the materials up there. Asteroids are very common in all systems and they provide a lot of resources. They will be a strategic resource and the only way to sustain a space civilization. This stage will be about creating the procedural asteroids, create the data structure to save their details and create the systems to later on allow activities like mining around them.
What's next?
This is up to you. If the game gains some traction and the development goes well, as I progress I'll be adding new steps, with your help and your feedback we can give a direction to this project.
