The ONLY Sonic game I've beaten 100% is Sonic Adventure, with all emblems and everything. I've completed the main game of Sonic 1, 2, 3, CD, SA2, Heroes, Shadow, etc but didn't get all the emeralds, emblems, A ranks, etc. Sonic 06 was the first Sonic game I didn't even bother completing. I beat Sonic and Shadow's story but I ended it there. Silver's fucking ball rolling puzzle was just ridiculous and frustrated me to no end.
