To be specific about what I've been doing:
1. Once outbreak starts, go check if any of the outbreak mons are shiny. If so, catch shiny. Then,
2. Return to a base camp and save. Return to Jubilife.
3. Go to leave Jubilife---if the outbreak for the mon is still going, head in and repeat. If the outbreak has disappeared or is replaced by a different mon, soft reset and try again.
Thank you very very much for this! I don't think I completely cracked it but I managed to use it to get two shiny Teddiursa right after getting Arceus, ironically immediately before I got my shiny charm.
Talking of which! Just finished completing the Pokédex; the only 'major' things left in the game for me are Manaphy, Shaymin, Darkrai, Rank 10 and I guess the old notes Ursaluna finds. I have reached what I would consider absolute completion before bonuses! I basically hunkered down the night I got this game and played non-stop; having left off at about 58 hours playtime.
Now I generally like every Pokémon game that comes out. Some a little less than others (a few pre-third paired versions feel a bit bland, do not like what USUM did to SM's story), but I do find all of them to be fun at worst; the thing about Pokémon always being the same game is that it's the same
good game and that's pretty much how it gets by, because you can always guarantee some kind of good time with it and at least some new creatures you'll love. And that's all well and good! But it is basically
the same game, and while again I do like say SWSH and XY well enough, they don't do a whole lot for me, you know? And I feel the need to say this whole "I like all the Pokémon games but they do get a bit samey and boring after a while" to emphasise that the main problem I've really had with this series is the formula and pattern it'd gotten itself stuck in rather than the flaws of any individual entry -- and Legends Arceus
completely smashed through that and won my heart!
Admittedly it was probably never gonna have a hard time? So much of it is set up to appeal directly to me -- I'm a Gen 4 baby so hell yeah I'll take a game that is so amazingly emphatically in love with Sinnoh rather than starting off a new direction with Kanto again; it feels like a bit of a dream to have any Pokémon game take place in the past and explore a game's history this directly; the main gameplay focus that it expands on greatly from the main games is Pokédex completion which has always been the funnest thing for me to do on any new adventure; they even throw in a new Decidueye form as a starter?? Someone at Game Freak got a portal into my brain or something? New Kami was a bit random though, dunno where you got that from...
So all of this was set up to make me very very happy to begin with, but even beyond that Legends Arceus was continually impressing me with its art direction, all its little touches, the way it recreates the region and dex in an entirely new way which is rough enough that you do see it as the same thing but allowing for natural environmental changes in the years between this and DPPt, how downright cinematic it is, how
tough it can be at points (I know you can refight Arceus! I don't think I will any time soon!), how imaginative everything was... it's a bit hard to believe this and SWSH have only a couple years between them, it is nuts just how good this game is and how
excited it made me for Pokémon again. I have not been this happy about this series in so long and it turns out all it really needed for me was the best love letter to my childhood region that I could ever hope for.
I don't really know what else to say. I basically cannot believe this game exists; it feels like something plucked straight out of my dreams and like something that could never have happened in the current climate the Pokémon franchise finds itself in, and is so wildly different from what we've been seeing recently that it gives me so much hope for what we might see in the future as well! I'm already hearing that there's reliable leaks of DLC later this year and that this game had the second best launch of any Switch game in Japan, so it certainly looks like a brighter future has been heralded right off the bat for this series. I'm not sure what direction it'll go in in the future (a Kanto-based one seems inevitable, surely? Maybe they'll even create
another entirely new type of Pokémon game in another genre?), but suddenly a lot more things seem possible, and I'm very excited for this series again and just really really happy to be playing a Pokémon game. This one knocked it out the park imo!
