Steamdb https://steamdb.info/app/427520/ never recorded a lower price than 25 € (which is the initial price before raising it to 32 €) on Steam. Maybe such a special deal was organized outside of Steam, possibly Humble or GOG. Game is also available on Switch, but I doubt it would go on sale there. On https://gg.deals/game/factorio/ it lists “Official Stores low:
20,00€ Ended 7 years ago”. Weirdly the websites price history shows a lower Steam price at launch. Feb, 2016 initial price of 20 € on Humble, then shortly after on Steam. Then April 2018 on Steam first price increase to 25 €.
