I just loved the "Race to the finish" missions. There were some moments of greatness in that game for sure. From surfing on a plank of wood to riding the rainbow roads. Awesome indood.
I hope that you'll start out somewhat faster in Black Knight. Having to upgrade just to turn and run faster wasn't a very good idea IMO.
Oh, and you have the ability to play as Knuckles and Shadow in Black Knight, although it's just optional. Still, I know who I'll be playing as!

Oh, and I've added anyone who joined the Squad as a friend. I just figured that if you love Sonic, you must be pretty cool.
