Palkia and Dialga are gigantamaxed and a raid battle.
Giratina and Arceus have and post game event
New Max move; Max-time&space, both switch the target atk/sp.atk if used by palkia or def/sp.def if used by dialga
Remakes are not in let's go style, more like a continuation of the SWSH.
No big wild area outside of the undergrounds and mt.coronet.
Underground now works like raid area, there is plenty of them in the region, but all are generic and have a raid mon as a boss.
Rotom has gigantamaxes.
Arceus has a new lore and new role and a special orb item.
