Seriously why. Sonic and the Black Knight was the last one and it was also the last time you could beat the final boss to a kickaas buttrock theme song. Why don't we have this anymore?
I honestly didn’t know that about CD. I didn’t know a single soul with the add-on, let alone the game. I only played it once a couple years ago. I genuinely didn't like it at all. I have forgotten most things about it aside from really not liking the time travel mechanic.
