So far, this sale is actually pretty decent. Lots of big titles are 50% off. Though I do remember the steam sales when brand new games were 60% off and older games would easily hit 85% off. Might have to finally grab Nioh, Nier Automata, Rimworld, and a few others.
Rimworld isn't on sale...
The publisher apparently said they don't plan to put it on sale implying for years.
