I didn't say I agreed with the Grandia 3 comment, but some of the best looking PS2 games could rival this.
Regardless, it's nowhere even close to PS3, so saying "better than PS2" is not high praise.
The Switch is capable of sprawling open worlds, this having linear routes while still having muddy textures and blocky hills in the distance is a travesty.
Again no they couldn't.
The graphics in these games are certainly not the best the Switch has to offer I agree with that and if we are talking comparisons with PS3 games then Pokemon still has better lighting and shaders but some PS3 games have more detail and more complex geometry. Some PS3 games look better than BotW in some instances so being compared to PS3 is fine. The Switch is only 2-3 times more powerful than the PS3 anyway.
