I recently saw the new design for Spyro in the upcoming Skylanders: Spyro's Adventure and thought it looked awful.
Being relatively new to gaming I get the impression that rebooting older franchises and ruining them happen quite often.
(I don't know if the new Spyro game is bad, obviously, but this picture isn't exactly making a good first impression)
So my questions are:
Do you know any examples of good or bad reboots?
And what do you think is the key to making a good reboot?
