Game looks great. Ive been playing for hours nonstop and the only issues ive had are very slight frame dips and shader glitching that happens once and awhile. Ive never once had any of these obscene crazy glitches you see online that were likely filmed before the day one patch or on the leaked game's ROM. And this is with a launch model Switch that has never been docked while playing this game. The issues I specified shouldnt be happening of course, and I am not shamelessly defending Gamefreak to promote the game. The game is not perfect by any means. Still, don't listen to the people saying this is a horrible pokemon game. The game is very fun and despite the mild technical problems it is a overall improvement upon the last gen (both Legends Arceus and Sword and Shield) in my opinion. This includes both gameplay wise and graphics wise.
I think it is unfair that people are giving this game one to two stars over things that, at least in my experience, are not even REMOTELY game breaking and that are barely noticeable when there is so much more to the game.
