Pokemon Black: I love it and hate it.
I love it since it was such a great and innovative game when it was released. The Pokemon are great, the story is fun, and the post-game is chock-full of stuff. However, it's easy to hate since its main feature is its Wi-Fi connections. And the day after I got Black, Nintendo Wi-Fi support was removed so the Entralink and all that is forever barred to me.
i never touched the entralink once and don't feel as though i'm missing out
