New story line to add more tech and longer games

I would suggest that you edit story to say that you are a group of forgotten people left on earth as it eventually dies. Your only hope for your offspring is to get to a pre-existing colony on Mars.
You now need 5 launches (add extra tech, material for each launch to build space platform, then rocket assembled in space to mars, then fuel etc , and the future launches to load people into rocket as you shut down your industry.
This would give people like me time to enjoy the creation you've made.
Could add a new building's that have to do with space industry. Aluminum would be cool too lol.
I only say this because I've played your game for years now and I do enjoy starting a new map I also like playing with what I've made for awhile longer but Labs have been shut down for a long time and factory and mines are grinding to a halt because I have huge stockpiles of parts , just the way I play game maybe and this seems to me to be a fairly easy add on with smallest amount of work.
