How far in space can you go with this game? I imagine it hasn't a galaxy as big as No Man's Sky and only known technology is used for rockets and engines, isn't it? Is there any kind of anitmatter drive that allows you to leave solar system? I know that currently antimatter costs about 30 billions per gramm, but anyhow a simulator can overcome this
I ask because using the current chemical propeller engines for spacecrafts is not going to move us very far and improving those 'conventional engines' is not a progress. The first place to make people convinced about that is such a type of game IMO.
