Sonic 06 did have the potential to be the ultimate Sonic epic it was hyped to be. I think that if more familiar characters had been used, the main villain was the now truly evil Eggman, and that they had forgotten about the evil Shadow look-alike, I would've liked the story a bit more. But I can live with a bad story. It was the glitch-full game play that really ruined it for me. I'm used to Sonic games with a horrible camera, but Sonic 06's was just ridiculous.
I never bought a PS3 (The other system I have) version of SU. Since I'm usually a Nintendo shipper, like yourself, I always buy the Wii version if it's available on all consoles. After playing Secret Rings to death, I was somewhat familiar with the gesture based homing attack factor, so the motion controls weren't all that horrible for me. But, those night time levels killed the game. Why on earth even put them in? If SU had been made completely of "day time" levels, I would've called it the best Sonic game since SA2. I really had a blast with those levels.
I'm glad someone else likes SA. I hear a lot of objections to the Voice Acting, but I think they did it well. However, I much prefer the Sonic X VA. I think that Jason guy does an excellent job portraying Sonic's "Live free, die hard, carefree" attitude.
I'm quite impressed with your Sonic Comic collection. I've only been at it since issue 150, so you're way ahead of me. xD But Scourge is a wicked awesome character. A true evil opposite of Sonic (Shadow turned out to be more of a neutral guy in the end) would be great for the games.
