What ORAS did was establish the entirety Gen 6 as being part of a different timeline from Gens 3-5 (Gens 1-2 are an entirely different timeline, themselves), the so-called "Megaverse," if you will. Of course, this was mainly done to explain the existence of Fairies and Megas in Hoenn, but not Kanto, Johto, Sinnoh, and Unova, but it ended up causing as many continuity issues as it fixed.
You know, quite a few people actually expected them to make a "WaterBlue" or "ThunderYellow" after FRLG (especially since FRLG lacked all of Yellow's additions). After as blah and barebones as FRLG turned out, I almost wish they had made one.
Even in sprite form, he's a cutie! {<3} I also love his GSC sprite, where he's clearly wearing a skintight catsuit (which gives me dirty thoughts, LOL ^_^). And, he was so adorable in the anime, too. They depicted him as he was clearly meant to be in the games, a kind-hearted do-gooder who stands up for what's right, rather than the brooding, "badass" anti-hero Adventures and certain fans want him to be. :rolleyes2:
So, you started with Gen 1, too? What was your first game? Mine was Yellow. Got it for Christmas in 1999, which I just realized was over 15 years ago now. {D:}
