I went ahead and bought a bunch of indie games, picked up Darkchaser, Oxygen Not Included, and UFO50, and also grabbed Cities: Skylines. Got used to the launch prices of some AAA games, buying these discounted low-priced games really doesn’t hurt much.
I can only recommend it. After about 60 hours I finally landed on vulcanus and I’m now experiencing the feeling of how it is to getting used to all of these long and complex Ressource chains.
