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.
Not on steam, but I bought Haven and The Talos Principle 2 on GoG.
I already played Haven on GamePass a few years ago, but I wanted to own it because it’s very good (also to support the developers). As for Talos, I played the original twice and absolutely loved it, so I’m eager to play the sequel.
