I would get Sonic 06 fixed. The game had potential but was glitched to Video Game Hell and back. The Game's Story and Characters were fine but if the game was expensive or not on my current gaming system then i wouldn't buy it. However if fixed, it may be fun.
Because the game is to expensive and when you play it you have to use an older system. There will be hackers in your system and that would mess things up. The quality would not be available and the graphics suck. I like the other Sonic games better and can't compete with the original.
