>Games are called Hope Diamond and Dream Pearl aka HD DP
>Release for the 25th anniversary and 15th anniversary for DP
>The National Dex actually returns and SWSH is updated to allow the remaining Pokemon. They advertise this like it's a huge deal, when it was once a standard
>Starters and Gym Leader/E4/Champion aces get Gigantamax
>Instead of the Red Gyarados report, you watch a report talking about Dynamax arriving in Sinnoh and how the lakes may be related to it. Lore implies that Eternatus awakening in Galar caused power spots to form in Sinnoh
>Barry is interested in Dynamaxing and wants to investigate Lake Verity
>Rowan gives you the Rotom Watch (known as the Rotch) which includes the Pokedex and functions such as displaying the map on the bottom right corner
>Dawn/Lucas has a character arc where they feel like they're forced to replace their father as Rowan's assistant and become a second rival who uses the weak starter
>Y-Comm, Camp, overworld encounters, PokeJobs, forced EXP return from SWSH
>No league cards, but ball capsules return
>The parcel you give to Barry is the Box Link
>The Rotch company president upgrades your Rotch to allow Dynamax
>Roark gives you the Escape Rope
>Once you defeat him, he gives you the Explorer Kit which allows to enter the Sinnohverse
>Sinnohverse replaces the underground where it's a Wild Area with Pokemon you couldn't get in Sinnoh. You can mine for items and create secret bases similar to ORAS
>Instead of HMs, you get the Rotom Bike+ which gets upgraded
>Contests remain the same. You collect stickers instead of accessories and decorate a photo because GF is lazy to make Pokemon wear accessories. Dancing remains the same but looks awkward as it's the models tilting and jumping
>Cosplay Pikachu returns and Cosplay Eevee is introduced
>Poffins replace curry. You get a Poffindex
>No Battle Frontier. You just get the SWSH Battle Tower and the IoA dojos replacing Pal Park
