The closest we'll get to having Perfectionists are those Cool Trainers or Ace Trainers haha usually having varied teams that are high leveled & they're confident in their Pokemon :) the games are too "family friendly" to have a hard mode...your best bet is in these fan made games.
So is it safe to assume you draw & write comics, perhaps manga, on the side, hmm? It would be really great if it's true :D I do have a long-running project I've been doing on & off for some years now, but I'd rather call them doodles than a full-powered comic haha
I got to see the video & just from first impressions, Sword & Shield look fantastic. Galar region, is it based on England? The look of the country side, that tower in town which reminded me of Big Ben, the male protagonist entering a football/soccer stadium while wearing what I thought was a Goalkeeper's kit...maybe I'm reaching (^^'' ). I just like finding out which real world places the regions are based on (Gen 1 & 2 being Japan, Gen 3-5 not sure, Gen 6 France & Gen 7 Hawaii). The starters look cool, I liked their artwork...it had a Gen 3 feel to it. You can only hope their evolutions will look like proper evolutions & not "next form", if that makes sense haha
As cool as the Switch may be, I know I'm not getting one any time soon. Gotta consider my location & of course - money. I don't have a 3DS, same problem, so I had to rely on the Citra emulator & it somehow manages to run on my non-gaming laptop haha. It's why from the time Let's Go Pika/Eevee came out for the Switch I have felt like perhaps my journey of keeping up with the Pokemon games may have ended with Sun/Moon, because I got to play that generation. Gen 8 is beyond my reach.
