The only one who has Pokemon as a game in it? Probably not. I mean I can't say for sure but if we can have aliens and samurai here then anythin's possible.

...actually, if you wanna look at it that way...who's to say that we're all not just a game in some other person's world? Like, what if I'm a game character too? Holy shit that's weird! I don't wanna think about it! Then that means that everything I did back home was all scripted!!
