Every Pokemon game I've ever had, I eventually ended up losing...about 7 games in all with my latest being SoulSilver (I didn't get Black nor White). So I officially do not have any Pokemon games right now. Have you ever lost a Pokemon game?
Yes. I lost my original Ruby and White versions, and both of which had a bunch of my favorites.
I ended up buying a second White version, and between my White and Black versions, I was able to re-train all of my original Pokemon. As for the Ruby version, my father found one in one of the cars that his dealership had to fix up and sell, so he gave it to me. (It didn't matter much, though, as I had already played a lot of Emerald.)
I lost my ruby version once. I found it again since then. That's all I've lost. My brother, on the other hand, lost his Diamond and Platinum, the latter of which he had a Shiny Gastly, his first shiny, caught days after I got a shiny gastly of my own.
I lost my original Diamond version along with the ds and I was so annoyed with all my pokes that I had trained up and lost but instead I got a new version and I am much happier with with whats on that now
I lost one (a label-less LG with my first GBA) somehow. It might still be in my garage somewhere, but ever since the movers came with my family's stuff it disappeared. Been nearly 2 years now, and it's a shame since I think I started a new file after I bought it (it first had a completed file on it).
But I destroyed two others: a PAL emerald w/ dead battery which eventually started constantly crashing before I could save (right after I got the 8th badge so I never got to E4). No big loss as my DS & GC games are NTSC (I already corrupted my original file w/o thinking), and I couldn't grow berries. Then there's Platinum which I got new. I can't even remember what was going on in the BF, just that I had enough and yanked it out with the power still on... FMS. D:
