After all, in a “tough” science fiction game, you would freeze to death in space.
A good example: we have studied many different types of fuel, the design of gravitational engines … I have read scientific articles on quantum physics, on the curvature of space. After all, you can’t just be transported somewhere, you fold the space “towards yourself”.
We played this version and decided that this system punished players too severely. The ship was running out of fuel and it became impossible to continue playing.
So we changed it not long ago. Now the fuel in your ship and the force of gravity only limit the distance you can travel at the same time. But don’t run out of fuel.
