I'd point that (as I've stated a few times) the issue isn't tecnically the artstyle.As angry as some people can get about the art style, some fans and youtubers (shofu comes to mind) was asking for a style EXACTLY like this because he hated the SWSH format. Sometimes we forget in our little bubbles how big and varied our opinions and wants really are; for some this is a dream come true, and for others, its a living nightmare, kinda fascinating to see it all play out.
One can like or not like the chibized style (I like it, personally), the main reason for people being angery at it is that from the few bits of trailer we've seen, it's of very poor quality.
Let's Go more or less did the chibized artstyle with 1:1 map recreation very well.
This one so far... not so much.
Obviously this (like Arceus Legends) is early footage, might be improved by the end.
Or at very least, I hope it is, because I'm not fond of watching hats with feet.
Bare in mind I'm one of those that will actually buy this regardless since gen 4 is the only gen I haven't played in some way and ( *flings a cookie at Pikachu315111 *, don't worry i still love you) I'd rather spend 60 bucks on this than buy a DS + the originals or even look for emulated versions because I am that lazy, and I would like getting something a bit better than what's shown, even though I am actually in favour of both the 1:1 recreation and the artstyle chosen.
