>>52645943I would have for gen 3 but my copy of Fire Red was fucked and deleted my save file (and broke my poor child heart), so I lost all my original gen 3 pokemon. I also lost my copy of diamond during a plane transfer, but when I got Platinum i've kept my Infernape with me in every game since. Infernape being cut from SWSH genuinely was the tipping point for not playing it at launch.
Since then i've gone back, finished the dex in gen 3 and moved them all up to Home (although I used PKHEX for 3->4 and 4->5 because fuck moving 360-400 pokemon 6 at a time. That mechanic is probably why I don't have as many of my original gen 4 pokemon still.
