Dunno if this was posted already, but it got a decent reception in the Unleashed thread:
Big the Cat is played by Jon St. John...who also plays Duke Nukem.
Other Sonic related stuff:
In Sonic Heroes, Espio is voiced by Bill Corkery. His wife Emily and son William play Charmy and Tails respectively.
In Unleashed, the Day Stage theme of Mazuri is a remix of the credits theme from Sonic 1 (Master System/Game Gear version).
Again, in Unleashed (like someone above pointed out), there is also a Dreamcast in the cutscene before the final boss. Next to it, apparently, is a copy of Sonic Adventure, only with Eggman's picture on it and renamed to 'Eggman Adventure'.
