I played the free demo of Factorio for about 10 hours and got hooked. Waited a bit to see if the price would go down, but it didn’t and I didn’t care. Bought it at full price and sunk a few hundred hours into it, which is some of the best entertainment ROI from a cost/hours perspective. It turned out to be a bad ROI from a general life perspective since I didn’t do much else during that time, so be careful to not get too addicted.
