It's like this when sonic the hedgehog came out he was #1 and I do like him as #1, then came tails which is #2 and that was in sonic2. Then came sonic and knuckles and that's when I decided that knuckles was going to be #3. Well I didn;t know about shadow and didn't have any info on him because he wasn't for sega genises. He was for the other systems that cost alot of money which i don't want to spend. But I do have a bga and i do have the game sonic battle, in that game u can play shadow the hedgehog and i was happy. So now sonic is #1 and shadow is #2 and tails is #3 and knuckles is #4. The only reason y shadow is #2 is because shadow is sonic's shadow, and plus everyone has a shadow and that's sonic's shadow and that's why he is called shadow. I have the game sonic the hedgehog for my sega genesis, and that's 2d. When i heard that there was a game called shadow the hedgehog i had to get it, but there was a problem it's for ps2. I wonder what the game would look like for sega genesis in 2d.
