Wild?
Hmmm,I dont Think So.Maybe we could have the Johto Starters in The Casino.Becouse we can get FR/LG and R/S/E starters in the games,so Johto starters in Casino would be a cool idea.
Probably not going to happen, even as prizes in the casino. :/
Since all the starters are obtainable in the current games we've got, and d/p will be backwards compatable, trading will most likely be the only way to get the past starters.
It would be cool! But mabye not in the wild..but mabye as a special event or mabye trading something...but I do like the idea of getting them in the game!
I think having wild starters would be nice, but only one generation's worth. I'd make it wild Chikorita/Cyndaquil/Totodile because they're the toughest to get (if you don't use Colo/XD, you have to complete the Hoenn Dex in Emerald just to get *one*)
