Celeste is great. I'd second that recommendation highly and throw in Hollow Knight as well. I've got almost 100 hours in it and watched less than 5 minutes worth of cutscenes or exposition. It's just pure gameplay and the difficulty gets pretty unreal. There's a ton of other great indies out there with the same, turn it on and play. I'd given on gaming for a while. These new ones have gotten me to enjoy it again.
