>>55783481100%, I'm replaying platinum for the first time in ages and getting around Sinnoh isnt even as bad as I used to think, you can get around pretty fast actually. And by the time the story does have you backtracking a lot, you have Fly. I was almost surprised how quickly I've gotten through the game because I remember it feeling way longer as a kid. I think time and memories just inflate how big and insurmountable Coronet feels.
similarly I think the hate on Hoenn's water routes is way overblown.
