He's obviously got a point. Whereas with Links Awakening you can really appreciate the art (despite the blur banding), I don't feel BOTW or ToTK (from what I've seen) are 'beautiful' either in art style or despite technical shortcomings, just inm the same way I don't consider Genchin or Persona 'beautiful'. The switch already struggled with XC. Link's Awakening was great, Animal Crossing is great, Mario Odyssey is a bit up and down but still miles better.
While we can appreciate the technical accomplishment of this game running on the switch, Witcher 3 is what the benchmark is graphically for a first party still. Sure, it's doing a lot more with physics under the hood but is it really enough? We compromise using the creation engine of course but not to this extent.
The simple fact is that while the Switch translates well to their core soft art franchises, if they are going to expand their other IPs in breadth and scope it's not fair to expect those fans to be happy with 'best efforts despoite the hardware'. If they want to deliver those experiences then they have to provide the hardware to run them. Commit to one or the other. It's not fair to say well, this is all we can get out the truly awful hardware so you're going to have to be happy with it. No one is expecting Forbidden West visuals or RDR2 but there is a baseline that art style doesn't mask.
The argument is not should we be impressed that the Switch has ToTK running on it, the argument is shouldn't Nintendo be providing hardware that allows the devs to make a game that appears it came post 2014 and not have to sacrifice basic graphic settings in order to get it to work.
