I want to play factorio but I lack a goal

[mrvn]

I found it useful to have a Factorio pause. The need to build something came by itself.
I heard also trying multiplayer might be useful.

jep ... after Multiplayer with wife, reaching 5k+ science per minute we stopped, as frames went down to 30... didn't play last half year. I started now alone again, 100h into the map and not a single rocket launched. I prepare everything for 5k science and want to turn it on at once.
Lets see how bad that works out

I remember there being a mod like that, where you have to build the factory and then hit the start button and it measures how long it takes to launch the rocket or some other victory condition. Then you can reset and try to improve things to reach the goal faster.
