Crayon Shin-chan

Apparently much of the jokes of the source material are impossible to translate to other languages as they are tied so deep into the culture. Likely the case with the games as well, so any translations would likely change the tone significantly without including tons of editorial notes on what everything means and where it comes from and why it is actually thought to be funny. Even then you'd probably just go WTF at it and wonder what the creators had been on.
