Death. Pokephilia. Crime. Meal. Stuffed.
5 sort of taboo things in the E world. I do think we see some thematic elements (like Death)...but how do you kill a ghost type? Or eat it...
As such, should Pokemon grow up a bit and offer some darker alternatives?
That was interesting.....
Some of that stuff will never happen, but eating them and using them for crimes sounds understandable. Hell, Pikachu is a rat, will they ever use rat poison to get rid of some?
I don't think Pokephilia would be that big of an issue, if it was even an issue at all. I mean, Pokemon are just that world's animals, so while it probably would happen eventually, I don't see it as being a common thing.
Farming and crime, on the other hand, I could see as being pretty common.
I think all of them besides Pokephilia could happen. But I don't think the'll ever put it into a pokemon game. Well number 3(The crime one) was already done in a way, pokemon ranger shadows of almia. They kinda did it.
