Oxygen Not Included has the same sort of effect for me and my experience with that game has kept me from picking up Factorio. Once you start getting into ONI's automation tools and design optimization; time just ceases to exist.

It remains the first and only game I have ever fully removed from my Steam library (not just uninstalled) after purchase.

ONI is great, yet one 'game' is much longer than Factorio. I bet you can launch a rocket much sooner in Factorio than in ONI. Also, I found Factorio easier and less stressful than ONI. There's no real 'lose' case and the progress feels faster.

+1 ONI. Truly a black hole that manages to warp time itself.

Also maddening being an early fan in beta, then repeatedly throwing out whole designs, plans and game files as they kept adding new things in the game and changing them.

However I've found ONI nukes my modest computer much more rapidly than Factorio. That was disappointing, coming from massive sprawling Factorio bases.
