FinalGamesDicas, I have no idea how much resources it all costs. I built truck station, top of it a train station, next to it a warehouse, then base building with the HUB and another train station at the back. It is a very large project and I'm not keeping count of all the resources. But it was a lot.

Regarding tickets, I only purchased decoration things. I don't purchase resources with tickets as it's a waste. So it depends on you what kind of decoration you want to invest into.

If you are new to the game. I would suggest building small with a room to expand. Once you unlock the top tier miners belts and so on... Then you will know how big of a building you need. Don't waste your time on decoration early on in the game as you will be rebuilding most of the buildings later on.

how much cost to make all of it (tickets and materials)

why are you in the backrooms?
