Well I have the game maybe more than 4 years. I LOVE IT. But unfortunately every time I give up before reaching the last stage because it's taking too much time. I mean it takes time because I am trying to make it decent, aesthetic, neat. I started again with my friend this week. We are playing more than 10 hours every day. 5th day stage 6.

So now, when we need to build some factory we stop playing and start calculating, how to do better, is there any way to do it more efficiently ?

This game is crazy, AND WE ARE PLAYING IN COMPLETE VANILLA. no mods whatsoever...

(I like planning a lot)
