I never caught or even seen an actual shiny for each game I played (Pokemon Ruby being the first game I played). Even after a decade of playing the games, I still haven't run into one, and I'm not counting those shines that can be easily found and caught like gyrados, gible, or dratini. I caught a shiny ekans in Pokemon Flora Sky and was was especially amazed that it was during my nuzlocke run through the game. Although it was a pokemon game, it wasn't one from Game Freak, so it didn't feel completely satisfying since I couldn't trade it between different games.

Edit: But getting a shiny gengar from Gamestop was pretty cool, but still not fully satisfying as finding one in the wild, but still great to it's mega evolution:

I think I may have encountered a shiny once. Before you get pokeballs, even. Like, wtf.
