>>34515037Even a lot of past 3rd versions had gamechanging differences. Note how Ultra S&M doesn't do jack shit outside of the extra sidequests etc.
Yellow had GBC support, updated sprites and Pikachu following you the whole game. Ultra S&M on the other hand is 90% indistinguishable. I don't even mean that in a general sense, I mean the casual player literally wouldn't even be able to distinguish whether it's the Ultra version. The biggest change is probably the battle music and the stickers scattered around the region.
They added a few new sidequests but it so easily could've been DLC it's insane.
