Its not just detail; animation is terrible in the 3D Pokemon games. Looks very amateurish.

Your welcome. On a bad note, you cutting my post made me realize I accidentally put "for the same of immersion and visual eye-candy" instead of "for the sense"   

Pokémon Go has the best grass/foliage

It'd be great, but then we'd never get anything done. If if takes this long even with 3DS-era assets, imagine how long it would take if the assets had to be more up-to-date. Sure, things could be better (a lot, actually), but looks good enough to me because of stylistic reasons.

Graphics have never been Gamefreak's strong suit. On a purely technical level the mainline Pokemon games have always been average at best for their respective systems. Gen 1 was not one of the better-looking GB games, gen 3, 4, and 5 were not among the best-looking GBA or DS games. The 3DS games really show how bad they are at working with the hardware, since they couldn't even get the 3D effect working except during battles in X and Y and didn't bother with it in Sun and Moon, all those games had slowdown, and they looked far, far worse than many games on the 3DS that had full 3d and better framerates in addition to much higher quality assets, effects, and animations.

I would hope that Lets Go and Town, by allowing them to get their feet wet in HD development, would lead to something better when it comes to Gen 8, but I've given up on anything close to the technical level of BOTW, Mario Odyssey, or Xenoblade 2 since it appears they are not getting help from Monoliftsolft like I'd hoped.

They could aim to have a samelike graphics design as Dragon quest 11 but it takes time for a company to fully transition to AAA non handheld games,they could suprise us with the coming pokemon game but expect it to be a slow transitioning.

The pokkenbwxample is just stupid cause they just had to fully animate and model around 25 charecters. With Pokemon, including the trainers, you'd need over a thousand animated models. If a Pokemon game was once every console generation, sure. But remember it took them an additional YEAR to transition from emerald to DP... GF is not exactly the best at programming, though they are Kings at charecter design.

I like how the games look now.

So before I respond to everybody I just want to make sure we are all on the same page. You guys all expect the Poke'mon to have the detail of Incineroar from Smash Ultimate, with the backgrounds of DragonQuest 11. Is that correct?

I will take GameCube graphics till the end of days on Nintendo Switch in exchange for getting more big games every year and more new IPs.

Maybe AI speeds up HD texture/animation creation one day, but in no way would I want slower game releases just for some marginal eye candy that my brain normalizes in 30 seconds.
