I take BGM into account when I play video games; if the music delivers the emotion of the moment it is in, it's a plus in my book. That said, Sonic 1's only good music were Green Hill and Starlight, whereas Sonic 2, over half of them really fit into the game. I once said that I would play a horrible Sonic game if it had a remixed Emerald Hill, Hill Top, Metropolis, and Sky Chase BGM in it.
I read the quote, and from what I got from it, it seems like Tails will not be playable. Which is a shame, because he is my second favorite Sonic character, after Sonic himself; he was once my favorite even.
