I honestly think they leech the series enough.
Maybe if they made some large changes to the game i might see it as worthwhile. Theres a good reason Pokemon reviews and the works have been getting worse and worse. Because sadly, they've just thrown out the same game over and over with minor changes.
I don't think a remake is needed but i wouldn't put it past nintendo doing it.
You're right, but the thing is, there's not really anything similar to the pokemon games right now. Because of that, nothing major is really "needed" to add into the main games, as there's no competition.
I agree though, it's getting a little old, Nintendo needs to come up with something a lot bigger than "night and day" next time around.
