I never bothered with BDSP or Sword and Shield's DLC. I think Sword and Shield the base game is perhaps one of the worst, gutted, empty and disappointing Pokemon games they've ever put out. The DLC should've been free, to make up for how badly the base game needs extra content. I would honestly give the game more praise and credit had the DLC been free.
Scarlet/Violet... There's a good game in there, but it desperately needs more work. I haven't beat it yet, because I got a Steam Deck this year and going from playing games on Steam Deck that are much more graphically intensive and then turning on Violet on my Switch and looking at how god awful it runs is such a turn off. It's hard to be immersed in that world. But I think someday they will remake it with competent performance capabilities and I will love it. Hm.... Okay It also needs level scaling. The idea of being able to run and do whatever you want doesn't necessarily matter when everything is locked behind a level cap anyways.
The superior Pokemon game on the switch is Legends Arceus. The catching mechanics in that game are bar none one of the most fun i've had catching Pokemon in years. The battles are fun. The useful of the Ride pokemon are fun. The story is good. The side quests were manageable. It wasn't perfect, but it's a damn good game that actually tries to be something more. In my opinion, a DLC with a story about Hisui starting it's first Pokemon League, adding in a gym challenge and a League challenge... Would've made this the best Pokemon game of all time and truly would've had something for everyone.
What a shame Scarlet and Violet had to follow up Arceus. AND took away several of it's fun mechanics. If Scarlet and Violet had Arceus's sneaking and active aim-throwing mechanics, it could've been so much better. The simple Quality of Life improvements that Arceus made that were then walked back on for S/V... I will never forgive them. And I don't want to hear the "They were made at the same time, there was no way for them to know what people would've liked with Arceus"... No. They messed up, in my eyes.
I think I would like them to either make a HD-2D game, which i've talked about in this thread 100 times. Or i'd like them to take more than a year in between games so we could actually get these games being better. 3D games have to be harder to create than the old 2D games. They need to take more time in between. Yes, people are going to buy it anyways. But... You could still choose to make the game good.
