Pokémon Moon- Fin
I don't think I developed quite the irrational fondness for this one as for X/Y, but I think that's down to liking the traditional structure and the sheer variety of pokemon you could get in Kalos. Gen 7 has some pretty great quirks- in particular these characters are complete dorks and it's pretty great. Team Skull fits right in there, it's a pity they don't get to do more in a way. And the back and forth structure between totally-not-gym-leaders and the Totem fights is something I can appreciate in a "well they wanted to change things without altering the core gameplay" but the constant feeling that the game was taking me by surprise with typings and the like was kinda off. Also as the game went on the Totem fights just utterly fell apart in terms of being a meaningful barometer of strength, which is a bit out of place with them taking the spots of half the gyms.
They are totally trying to sell you on a Trainer/Lillie pairing. The trainer's vacant smile undercuts some 30% of all scenes in the game because of this. And all the other ones but it doesn't matter nearly as much there; the other characters are goobers, so the scene is already silly. Hau in particular should get a mention here, he's the best.
8/10 stuff I think? Seems right.
Primarina (really, female name for a pokemon that's 85% male?)- Spend a long time just kinda warming a bench eating passive EXP in the middle. Not really bad in that time, just has some weird move lag since it's so lopsided in favor of SAtk. And then it gets a unique Z Move upon final evo (a few levels earlier than the norm, 34 vs 36) and all is well. Except of course that happened around the time I started finding cool stuff I wanted to use. Not much of a slugger but good at what it needed to be.
Snorlax- Crazy good early and part of the reason Primarina took a seat rather than trying to overlevel harder. Also gets a unique Z move in the mid-30s (if it's the giveaway munchlax anyways), which boils down to "Trade a use of Giga Impact for a version of Giga Impact that doesn't have a lag turn". Yes please.
Mudsdale- Stamina is really good on paper, in practice most enemies have mixed offense in this game so you don't get to use it TOO much against Kahunas and the like. Movepool is a bit monochrome... but it also STARTS with Bulldoze and gets EQ at a reasonable level. Despite coming up short in the very end just due to not having too many opportunities to really shine it feels like the strongest Alolan pokemon on paper, and is caught really damn early to boot.
Haunter (Retired)- Never really came into its own, I think I mostly raised it to haunter just in case the game asked for some nonsense pokedex counts later on.
Umbreon (Retired)- Big help for a dungeon or so after it evolved, then I found some cool stuff...
Mimikyu- So cool. Needs like 5 levels before it can do anything (you don't get good physical TMs it can learn so you need L37 to nab Shadow Claw), but adequate damage in good types and Disguise is just so handy.
Skarmory- Never really used it before. For some damn reason it learns a bunch of Special flying moves and it can't learn Acrobat so it's stuck with like Sky Drop on that end, and Steel... is a better attacking type now at least (Alola has a fairly healthy Fairy population), but still not great.
Exeggcutor (Retired)- Tried using this, turns out it doesn't have the right movepool to cover the holes I had. Weird.
Lunala- Didn't see too many fights, and kept getting kinda OHKOed due to entry hazards rendering its ability moot, but hey that's my fault.
