Yes, Sonic CD, Sonic Mega Collection Plus, Sonic Gems, Sonic Heroes, Sonic Adventure DX and Sonic Riders are all playable on PC.
You can play it on the PC, but it's pretty hard to find.
My personal favorite sonic game is sonic advance 2, but there is a new game coming out called "Sonic Generations" were you can play 2D or 3D sonic game and play as modern sonic or classic sonic, if you want more info look on youtube ;)
You can try going on SEGA.com and click on play sega, make an account, and you'll be able to play any old time sonic game online. There are also at least a few Sonic flash games. You can try a google search for "sonic flash game" or something similar, or try to find one on game sites like newgrounds.com or such.
you can only play him at the end of the game.
You don't because unless you already own a copy of the game, it's illegal.
This should be in sonic unleashed.
Sonic Rivals. hope this helps
At playsega.com you can play sonic the hedgehog 1 from the sega genesis just in your internet browser. You only have to be gold member what isn't very expensive. You can also download an sega genesis emulator with the sonic the hedgehog ROM to just play it on your computer.
Sorry kid... you cant play as Shadow or Metal Sonic. there not programed into the game.
First you need a Sega Dreamcast Emulator (For original Sonic Adventure) or a Gamecube Emulator (For Sonic Adventure DX, which is an upgrade of the original). After that you need to download the emulator AND the ROM for the game you want to play. Note that the emulators are not Nintendo/Sega approved or licensed.
NO.
Super Sonic is not playable in this game.
