Indeed, not to be completely throw Klei under the bus, but I started playing Oxygen Not Included, and the simulation quality is night and day. ONI has race conditions, memory corruption bugs, non-seeded RNG, duplication bugs. You couldn't play a non-glitched playthrough even if you tried. At some point, you're going to make an infinite spill or a liquid lock on complete accident. Meanwhile factorio allows you to benchmark it by opening a save and running it for a set number of ticks -- it's just that stable in its simulation. Not to say that ONI isn't a fun game, it has different elements (e.g. dupe management) that make it fun despite its instability.
