According to Japanese game site Andriasang, Pokemon Black/White will only pit players against new Pokemon until they finish the game's main quest.
New Pokemon titles are always a thrill to experience, but playing them feels a bit like adding a fresh piece of gum to a wad you're already chewing: The games don't really feel quite new because all-new Pokemon are introduced alongside piles of old favorites. It can be hard to let go of your faithful Charmander in favor of a stranger.
That's why Game Freak's Junichi Masuda is giving players a whole new experience with Pokemon Black/White. On his blog, Masuda states that only brand new Pokemon will be accessible until the game is cleared.
Not surprisingly, Masuda admits that coming up with a stable of fresh new Pokemon hasn't been easy. But he also believes that the decision will level the playing field for Pokemon veterans and newcomers alike.
