For those who aren't aware, Steam is currently doing a Singles' Day sale
Some notable sales are (personally):
* Spyro + Crash Remastered (if you didn't get it from Humble Bundle. Also available individually) - $54.32 - Link
* Shadow of the Tomb Raider: Definitive Edition - $35.52 - Link
* Divinity Original Sin 2: Definitive Edition - $35.72 - Link - Not the cheapest all time but still cheap
* Just Cause 4: Complete Edition - $36.23 Link
Please let me know if I missed anything
Spyro and Crash were recently $12 USD and they came with COD.
