[Sonic Heroes] wasn't originally going to be on the PS2. But Sony told Sega that if they didn't release Sonic Heroes on it, they wouldn't be allowed to release any other games on it. So they had to use the Renderware engine so that they could easily bring the game to the PS2. And the games weren't well optimized for the PS2, which is why Heroes and Shadow the Hedgehog are really bad on the PS2.
I'm pretty sure that whole thing irt "Sony forcing SEGA to port Heroes on the PS2" is a baseless rumor (and was created to defend Heroes as a game); as far as I can tell, Heroes was always meant to be on the GameCube, [OG] Xbox and the PlayStation 2 - if this and this are of any indication. I think the PS2 ports were just rushed or poorly implemented on their own terms (especially given other Renderware engine titles that were also multiplatform).
