KH worked because Disney was there, but not pounded. There wern't those painful gimmics like
"we have to lite the torch to get though the large underground tube like structure, Spyro."
"I can light the torch with my fire breath, Sonic, but you have to run really fast through this maze before the torch goes out."
(you can see that happing to can't you? Don't lie, we all can see it!)
You meet Alice (in Wonderland, where else?) and you play though a parrellel of the storyline with a few of the origional cast included. Done. No beating the horse to death, or even beating it porst mordom. It is done.

You move on and meet Merlin, he teaches you magic and give you a portal to visit a stuffed bear. Done.  It's not the character themselfvs that make the game, it's how those characters realisticly interact with each other (in the unrealistic environment)

And SSB would have been a hit fighting game no matter the skins they put on the toons, the gameplay is just that fun. (and since it's Nentindo, no-one has a voice actor, yay!)

All in all, a Spyro-Sonic crossover would not work (says the guy who laughed at the idea making warcraft an online game... oops on that one)

What black knight?

Martin Lawrence.

Please stop suggesting more fuggin' cross-overs, all the games that had cross-overs were good before they had a cross-over.

I tell ya it would be awsome if they made a spyro version of Sonic and the black knight or atleast a game were Spyro teams up with sonic like in Spyro oringe

No.

I played sonic and the black knight. it was fun... but.. wrong. just.. no.

Indeed
Maybe if it was the original non f***ed up sonic then yes.
original sonic owns

On a side note: No...It would be to much of a rip-off
