My biggest problem after owning a deck for a year is the controls. If you like to play PC games designed around a mouse and keyboard the deck is just a chore. I struggle to play games on my deck when the controls make playing the game take far longer than on a PC where I can quickly hover my mouse over things or click and drag. Yes it has trackpads but it's definitely not the same experience.

That said if it's a console first game then it usually works pretty well.
