>>36843645They're pretty solid. But what they don't have stands out a lot more than what they do have. They should have had the Battle Frontier, they should have a larger New Mauville, they should have had a longer Trick House, they should have had the storyline with both legendaries...
Those were so defining of RSE that omitting them makes it easy to forget all the things that were added: Mauville gets expanded, Sea Mauville replaces the rather generic Abandoned Ship and gets lots of new lore, the Delta Episode, Eon Flute flying, Mirage Spots, PokéNav Plus' QOL improvements (specifically the DexNav), having both bikes at the same time, underwater Trainer battles...
At some point you'd think someone at GF would have though it quicker and cheaper to just add the Battle Frontier instead, ADHD kiddies be damned.
