I think for a lot of games it helps to tune them the way you want to play. For Factorio I like to turn the biters to easy mode, add some convenience mods like ranged grabbing etc.

But after that I like to "speedrun" the game to see how quickly I can launch the rocket. My best time is only about 11-12 hours, so it's far off any kind of world record time, but it makes the game a lot more fun when I have a goal in mind, instead of just endlessly optimizing etc.
