If the Switch truly doesn't give a hoot about graphics and emphasizes fluidity of gameplay and intuitive controls, then I might consider jumping back into their ecosystem, depending on how many games they produce.
Outside of the Nintendo Classic Mini, I haven't had anything to do with Nintendo since the first version of the Wii. The problem I always got into was that my wife loves the platformers they have, but their action games didn't quite feel right to me coming from a PS/Xbox and PC background. I'm not sure why, maybe it was the emphasis on motion and unique game play rather than just using the buttons and stick to play a fun game. The graphics were behind the other systems, but honestly that meant nothing to me. The graphics were (and probably still are) completely adaquite for the games they were producing. I just felt the controllers were always a bit behind. I would love to find out that there is a system that has potentially dozens of deep games I've never explored.
Does the switch do backwards compatibility and if so, how far back?
Probably take me that long to save up for an OLED display. Those things look beautiful but are not cheap.
