I got One Step from Eden for 60% off, considering oxygen not included for 66% off. Divinity Original Sin 2 is $10 right now and I highly recommend that too. The Arkane Anniversary Bundle is $10 right now and is looking really tempting since I've never played Dishonored.
Still on the lookout for other deals, but it's looking good so far.
I just got access to dishonoured 2. But I recommend the first one. It's a bit dated now but it was a good laugh. I like a bit of steampunk so it helps nicely.
