With Crash getting remade, the inevitable question was always going to be: what about a Spyro remaster? Nothing has been announced so far, but that hasn't stopped Vicarious Visions from being a bit cheeky with an easter egg.
On the original version of Crash Bandicoot Warped, you could unlock a demo for Spyro by pressing up, up, down, down, left, right, left, right and square.
That code would open up a third menu option that would let you fire Spyro up, as can be seen below:
And as YouTuber ThornsofSerenity discovered on the menu screen for the Crash Bandicoot N.Sane Trilogy, if you enter the Spyro demo code, the highlight over the menu options disappears (displaying only orange text, instead of white when the menu option is selected). It only disappears over the Crash Bandicoot Warped options however, not Crash 1 or Cortex Strikes Back.
For reference, here's what the menu sounds and looks like before entering the code.
Nothing's officially confirmed, of course, but the fact that this happens over Warped and not the other games means it's likely deliberate. A good explanation could be that the developers chose to pop the easter egg in now, with a window to dropping the Spyro demo - or something else - in later. And given how well the N.Sane Trilogy has sold, a Spyro remake kinda makes sense.
Update: Accidentally referred to Naughty Dog instead of Vicarious Visions in the original version of the story. Don't shoot me, people. Or do. Comments are below.
