Im a bit of a grump.
The Diamond and Pearl remakes don't look great. The battle scenes look fine, but the overworld looks... wrong. The chibi artstyle tries to be a 3D interpretation of the pixel art, but it really doesn't work here. Not to mention that it barely looks like it is pushing the hardware, like Links Awakening or The Touryst. I really wish that they stuck with the same style as the Gen 3 remakes, or Sun/Moon, but cleaned up the lines. Its really quite ugly.
For the Legends game - im happy that Pokemon games are pushing the boat out, at least a little. But the game itself looks rough. Like, really rough. I get that the game is still in development, but this was not a great state to show off the game. The framerate looks terrible, and the level of detail at a distance makes the game look 2D past a certain point - not to mention that everything looks really barren - Its just hills and long grass - and the colours look really washed out. A lot of people are triumphantly saying that this is "Pokemon's Breath of the Wild", but BotW looks multitudes better, and that is a game from (almost) 4 years ago. Hell, Genshin Impact looks better, running on a phone. What is Nintendo's excuse?
Are pokemon games contractually obliged to look like the worst first-party games on Switch, or something?
