I know that there are mods which do what I am about to say but every time there is a new update mods become absolete and this will result in having to stop playing what I was just playing yesterday. Furthermore by the time the mods has been updated (if ever since some are not) there comes another update and the cycle repeats itself. If you are telling me not to update that is not an option as steam games always update automatically.
So the solution lies in having certain things implemented into the base game. So how does it go to start with implementing the textures of our Solar System planets into the game and throw some maps with them though the latter is less important as Galaxyforge allows us to do that. Having our solar system planets really adds atmosphere to the game and if it is included in the base game then it can be played online with other players.
This is not hard to implement. Many modders have done it in the past but at present it seems that there is no version working with the latest update.
