Well I have 3 thoughts on performance
1) I am fine with the power of the Switch. Perhaps it is because I grew up playing ps1/N64, but any game that is HD with a stable frame rate is good enough for me. The ps4 Pro looks beyond amazing. Pretty much all games are leaps and bounds better than the stuff I played growing up.
2) Graphics mean nothing without art style. The "prettiest" game I have ever played is Wind Waker HD. I'll take style over graphics all day long.
3) Games matter. I don't care how good something looks, what matters is how good the game is. And the quality of a game is 99% gameplay, controls and level design. Dark Souls 3 isn't the prettiest game on the ps4, but it is the best.
I would say that is closer to about 70% in the general sense. Storytelling has been a large part of gaming for a while. In some cases it could be an even 50/50 split. For games that hardly have much control or skill needed like Life is Strange, the story becomes even more important than the gameplay. Lots of different ways to enjoy a game since the mid to late 90s.
