Sounds like a really good deal! I've got all of the Witcher games, and they're pretty good. I'm not really a Star Wars fan, otherwise I would pick up some of the games while they're on that deep a discount! It makes me wonder how good some of them are for a non fan.
Ghost of Tsushima is a game I'm definitely keeping an eye on. I've unfortunately been disappointed with a lot of the recent PlayStation PC releases though, so I'm a bit wary. I'll wait to see what kind of discounts show up in a year or so!
