I'm not really aware of the newer generation of consoles, but I guess most of these have retro compatibility. Sonic CD (2011) is available on multiplatform. Sonic 1, 2, and CD received probably the best ports of the franchise: the Taxman ports. Feel free to point why you think a method is or isn't valid, as well bring any game you think deserved to be on the list and the respective methods to improve it. I don't think I need much more explanation. My main focus will be PC, but I'll try to add commentaries on other consoles as much as I can, but it's not that helpful when my last console was the PS2. By this, I mean the better way available to have the best experience on current hardware. So the main point of this topic is to bring the 'definitive editions' to play each, or at least most, Sonic games. The Sonic franchise is home to a list of games, some of them become instant classics, others become very forgettable, and most important, some received more attention and got adapted to our current days, others simply didn't. I've been with this topic in my mind for a good while, but given some recent events, I've decided to develop it better.
