Also, technically, Shadow really did die in the end of Sonic Adventure 2.

However Shadow had such a big fanbase that Sega felt obligated to bring him back in with Sonic Heroes and expanded more of his story in his own game.

Sonic Heroes can be regarded as an "Adventure" game (even though wasn't made for Dreamcast) but it was made mostly for the fans than a continuation of the Adventure series.

Personally, didn't enjoy Sonic Heroes all that much. I found character switching tricky as well as some stages as well as the really bright colouring put me off a little.
