Sonic Generations Final Boss
Sonic Generations is a good game and not just relative to other recent Sonic games. Relative to recent Sonic games it is unbelievable but even relative to all other games it is pretty good. Sure the story makes no sense and isn’t even internally consistent as it is a time travel story, but it provides the thin veneer needed to let us play as both 2D and 3D Sonic in one game, so it does it’s job and doesn’t really get in the way a whole bunch. If it also happened to use the time travel thing to ret-con out the whole ‘Sonic the Werewolf’ thing that would of been appreciated but I guess not necessary.

Neither of them turn into a werewolf in this game, I promise.
Now I’m picking on the story a bit but it isn’t like the story really matters in a Sonic game, they are primarily action games. So if I was able to change only one thing about Sonic Generations it wouldn’t be the story, even if I was allowed to get rid of all the awful parts of the series cannon. If I could only change one thing about the game it would be, no contest, the final boss.
