Oh yeah we still have that one. Sonic Boom, and Sonic and the Black Knight as well. (I personally liked Forces)
But 06 i still known to be one of the most buggy Sonic games ever. Thats why it is so crap in memory as well as;
Is it piracy if it was released for free? Not in my opinion, but I also think it's not piracy if buying it isn't owning it, and it's not piracy if you can't buy it from the original creators anymore.
