After 67 hours of play time and several more watching playthrough and tutorial videos of Oxygen Not Included (2019), I threw the towel again just before getting into space. Getting a near-sustainable base going was nerve-wracking enough, and I've sadly hit my cognitive limit regarding the planning involved in rocketry.
Despite this second abrupt ending, I'm still somewhat proud I finally managed to get to this stage of the game, but it did cost me pretty dearly IRL in terms of obsession-fueled late nights, and it confirmed to me that I'm definitely an implementor and not a designer.
