>>58188092emerald makes you go from mt pyre to mt chimney, then to slateport. then to lilycove which was right next to mt pyre the whole time.
and then later you have to go to sky pillar and back.
or how to get to lavaridge without flying you need to take a fucking cable car up mt chimney and then immediately go back down because of one stupid ledge.
or how the early game is extremely segmented because the second fucking gym is an island separated from everything else.
or that one series of sea routes with the currents that you need fly to retry because going on foot means doing a loop around the entire eastern half of hoenn.
real thoughtful region design there.
