This game is really hard to aim 1000g because of getting an S rank is impossible. It like getting a S rank is to complete the Act mission without dying. The lasted Act I got a S rank is Crisis City as Sonic, because on the last area, I having trouble dodging the objects and cars while being chase by fire tornado. Unitl I realize I can light dash the rings to go far so I won't get hit by cars. Sonic's Speed is not fast
, Silver's power is lack to control
, and Shadow... well he no problem
. For Rouge, she didn't use kick but she could use throwing bomb
. For the medals hunting, I go to youtube videos to location silver and gold medals. It really hard to location them on my own, but thanks for the person who made the medal location videos. I had 1000G in 4 years to completed it. This game is hard, but I enjoy it because I'm a fan of Sonic. Hope I play it again.
