Sonic Adventure 2 was ported to the Nintendo Gamecube before Sonic Adventure was.

And, thinking about it now, it confuses me, why would Sega port Sonic Adventure 2 before Sonic Adventure?

If anybody knows why Sega chose to port Sonic Adventure 2 to the Gamecubebefore the best selling game on the Sega Dreamcast (Sonic Adventure), say it in the comments of this blog.
