I really love the double vision of what appears to look like paint! Very effective!
The outlines, the colouring, the shadings and highlights, the effects, and the background are all very incredible and astounding!
I won every time in multiplayer when I played Silver in Sonic 06.
Nice picture though!
And Eggman apparently outran Sonic in a Sonic 2 level (which I think the game was programmed to do so regardless).
A lot of Sega fans believe Eggman is faster than Sonic because of game programming. lol
For Shadow, it's strongly implied that he does in fact share Sonic's speed and agility without his skates. Based off of his Rival Battle in Sonic Generations, it can be assumed that Shadow's natural speed is turned into fuel for his skates or something, because he still needs Rings to boost just like Sonic, and the energy is being blasted out of his skates when he boosts. Since Sonic's boost comes from using the Ring Energy absorbed into his body to amp himself, for Shadow it should work like his skates take the natural speed that Shadow has and converts that into the energy released from the jets in the soles, and the Ring Energy absorbed to boost adds more energy that the skates release, thus causing Shadow to blast off like a rocket.
Very interesting theory there about Shadow's natural speed, his skates and the Ring energy given. I can see how they all correlate to each other. He was slightly faster than Sonic in SA2B as well. I also wonder if Ring energy applies to Knuckles too. I know he's nowhere near as fast as those three hedgehogs, but he was pretty speedy in SA2B and the games before it.
