Factorio v1.0 has been released this week, in time to finish off my most recent map (with the Rampant mod for enemies and weapons).
It’s been over 4 years since I first played, and I’ve only recently learned the most important lesson for keeping it fun: Embrace the spaghetti. Don’t get annoyed and think you have to refactor all the time, don’t worry about things lining up or being the most efficient. Just keep building and expanding, it’s fun to look back at the mess you’ve made.
For fun, here are some screenshots:
