>>56647103They removed "Gotta Catch Em All" from the box-art (it was present in the English pre-release box art), so maybe they were planning a Dexit, but Masuda mentioned in an interview that they had already had ideas for the Kanto Remakes and DP during the development of RS. I think the Kanto Remake decision was mainly due to pressure from people like Tsunekazu Ishihara. GameFreak knew that the overhauling of the old stat experience system into the new 252 IV system and addition of abilities would make it difficult to transfer Pokemon from GSC, but they could've at least included all 386 (or 382, excluding Mew, Celebi, Jirachi, and Deoxys) in RS to soften the transition. Yet they didn't. They split them across multiple games and even console systems o milk the most money out of the most devoted fans who wanted to complete the Dex. Hence the lack of Ditto in RS, the arbitrary trade restrictions in FRLG and Emerald, etc. The Gen 3 games are still good for the most part and the Sevii Islands wouldn't have existed otherwise, but they made Dex completion deliberately difficult.
