Slightly related story but when I was a kid I had a neighbor who had Pokemon Ruby and wanted me to get Pokemon Sapphire so we could trade for exclusives. Eventually I convinced them to get me that game for Christmas one year, and since my younger sister was jealous of me having Fire Red all to myself they decided it'd be fair to get her a game as well.
That game? Well it was this little tittle I haven't heard of yet called Pokemon Emerald.
Yeah I was a little salty when I found out that there was a superior version with animated sprites and a Battle Frontier that my little sister got to play but I didn't.
Moral of the story: 3rd versions are confusing to parents and new fans. Actually now that I think of it that might be why they named Ultra S/M the way they did, so its clear they were the "better versions" in the title.
