Google has recently made changes to Stadia Premiere Edition recently, but they also took away something.
The new Premiere Edition bundle has a cheaper price this time around, which is now $100 instead of $130. It has gotten cheaper, but there is a catch: the three-month Stadia Pro trial is now gone. It still has the Chromecast Ultra and Stadia Controller. Pro is a high tier subscription, which unlocks 4K HDR quality and 5.1 surround sound. The monthly payment for Pro membership is $10.
Pro members also get access to several free games monthly, which currently has 18 titles.
