>>53275117HGSS is the most overrated game in the entire series whose entire identity is based around getting gated by daily events to the point of total retardation, like locking gym leader rematches behind having to call them during literal business hour weekdays or locking Safari Zone Pokémon behind three months of waiting. This is great if you a weeaboo NEET who claims that these bad choices along with completely trite shit like the Pokeathlon that doesn't even give you a ribbon or the Shiny Leaf quest are 'comfy'. Everything good about it was a direct result of Platinum.
Crystal was that low because it really didn't add much anything of value as a 2nd version. DP were the only international games that were able to connect to Ranch. SwSh also are that high because they're pretty much the first games where you can realistically train a bunch of Pokémon and not have to treat it as a full time job.
