So,I found something in Sonic 06 earlier when I was just messing around.After completing Wave Ocean as Sonic,buy the Antigravity and make your way over to the roof where Francesca is.Talk to her.After this,go find Ganiella across the bridge,as she has a mission for you to do.Decline,and do not talk to any other NPCs.Perform a skip to get into the part of Soleanna that is blocked off.Once there,go to the area near Aquatic Base.To the right of the mirror,on land,there's two men talking.Talk to the black one (I am not trying to be racist),and he will have Ganiella's dialogue. Actually,this man will do this with any NPC.If you talk to Francesca,and come to this man,He'll say what Francesca says.Here,you can accept the mission.After the loading screen,it'll load up Ganiella's next but of talking,and you'll see Ganiella herself.Finish the mission,and wait for the loading screen.You'll see the same man as before and you can accept the mission again.This leads to you being able to repeat the mission as many times as you like,and you can get infinite rings this way.This serves no purpose other than getting rings,so you can get tons of rings even before you go to Dusty Desert.I have no idea if anyone has found this before,but I found it and think it's actually really interesting. Let me know what you guys think.
All this was done on the PS3 version,so if someone could try it on the X360 version and confirm it works,that would be great.
