"Hey, I've come up with these version exclusive areas! Black City and White Forest!"
"Oh, that's good."
"Yeah, and the less people there are, the more useless it gets!"
"Er... wha-"
"And people go away if you don't talk to or battle them every day!"
"But how-"
"And only local wireless from the other version will bring them back!"
"But what if you don't have friends near you who play Pokémon, let alone the other version? And what if you want to take a long break from Pokémon?"
"Ah, who gives a crap?"
At least B2/W2 did it right later and got rid of that nonsense.

"A cameo is a small appearance of a known person with a minor role". So why do people call Dawn's BW appearance a cameo when she was a major character for NINE-ISH consecutive episodes?
