I've clocked ~2300 hours on this game. It's called 'cracktorio' for a reason.

The scaling up is so fun. When you launch your first rocket, that's just the start.

The goal is to build an enormous base, to try and launch a rocket every minute or even faster.

It requires elaborate multi-lane train/rails networks to sustain a base like that and it is awesome.

But you can build your bases any way you like and use any technology you want.
