So my thoughts after playing with it fit the first time yesterday...
I started with Path of Exile and Grim Dawn as my first games. The confused feeling only really lasted about fifteen minutes before I was in the zone. I know it's a simpler type of emulation but after reading so many bad reviews and thoughts I was surprised it was so easy.
The simplicity if the out of the box experience was a joy. Very streamlined and felt like it'just works'. Same with the ability to add settings, warn me if my controller isn't set up for a specific game yet, etc.
After about an hour of looting, it clicked with me that I was playing a new type of experience. If hard to explain, but it felt like i was aware that i was doing something that would be commonplace for the first time. I was playing a mouse driven ARPG from my couch.
These types of games were fantastic to start with. Not turn based, so I needed to be on my guard, but not twitch where I felt disadvantaged.
Can't wait to try more tonight.
