Considering that a lot of people would say that Spyro, Satisfactory and Back4Blood alone are well worth the price, I'd say it's pretty much a nobrainer.
But I have a lot of those games already and especially Supraland has a huge place in my heart. RPG Maker XV and even MAGIX Music Maker EDM edition are cool add-ons that I'd like to tinker with.
I'll get it today. The only problem is that you can't activate all Steam games in a single run, because the system will block you after too many activations for some time xD
