Hoenn sucks. IGN was right, too much water.
I've revisited Hoenn a lot (because of RNG/Ribbons) and every time "hey, this ain't too bad, why do I dislike Hoenn so much?" and then, BAM, I hit Lilycove and "I remember now"! Gods, so much boring ocean filled with shitty constant water spawns, exploration is dulled because the best things you can find are shards that might get you an evolution stone and everything blends into one another. Fight after fight of poor Swimmers with their shitty Water Pokémon.
Then, when you've just fled your 170054285474th Wingull encounter and finally reach Pacifidlog Town the game goes "hey, the water is evolving! You've now got ANNOYING water!' and you get an annoying puzzle that, if you don't look at the complete map beforehand you're basically redoing this goddamn section twenty times to get all the exclusive routes and items (and one of these houses the only trainer with Bagon so if you wanted to know this thing even existed you better do it!).
Finally you reach the hollowed out crater of a volcano (yay!)... dried up and filled with rainwater (boooooo!) and what does GF have the gall to inflict upon you? Yeah, you haven't faced enough goddamn Water trainers to their liking, here's the Water gym!
At this point I'm just so soured on the whole experience. Hoenn might just be the worst region for me, it's down there with bland Galar as clear bottom twos (can't decide which I dislike more)
