Are there any Pokémon games for the Switch worth picking up? I've got Pokken Tournament; I find it to be fun, personally. Are there any others that you guys might suggest?
Honestly? No. Nothing mainline, and barely anything spin-off.
The closest I can get to recommending a Switch Pokemon game is saying that Legends Arceus does something different that you may or may not like, and I still really wouldn't recommend paying full price for it. PMD DX is only debatably better than its 20-year-old progenitors, every single mobile game has been ported very poorly (UNITE especially) since they want to make their real audience (mobile gamers) very clear to the Switch so that they change over, and games like New Snap or Pikachu Returns either aren't out yet or have issues with filler clogging up gameplay.
Seriously though, either Legends Arceus or New Snap or nothing at all. Neither are worth 60 bucks, but they make for a few good hours of fun.
I'm not surprised that they're locking starters and all this OP shit behind DLC ("lmao what if we made a priority move that out-priorities the priority moves and also 100% flinches"- thank god this fails against normal moves) but honestly I'm glad to see everything else. More hard-to-get Pokemon being available more frequently is (almost) always a good thing (the only example I can think of where this is a bad idea is with shiny pokemon for very obvious reasons). I still don't know why TPC is so insistent on calling Starters "first partners", it's very awkward, but I guess it's a marketing thing...
The typings for both Paradoxes was... somewhat expected? Electric/Dragon was a shoe-in (even though idk why they're adding so many this gen), Steel/Psychic slightly less-so. That design seemed more pure-Steel or Steel/Water to me, but I guess I should've known better since every other Paradox has 2 typings.
"Legends Plate" Tera typing is cheap and dumb but once again expected as a marketing stunt and a natural progression of the power creep. Interestingly enough, I might actually be off-base calling it that? In this screenshot you can see that when Tera'd it doesn't change Tera Blast to be Super Effective, so maybe it's something else...?

Whatever it is, I think it's more than blatantly obvious that it has to do with Terapagos, so I doubt it'll be much of a thing in Teal Mask. I'm curious but unenthused. Hard not to be when I can't bring myself to care about much beyond true excellence or grave disappointments regarding this franchise by now but oh well lol.
