Spyro and Crash Bandicoot were what defined PS1's era (besides Final Fantasy, Gran Turismo and Tekken) so why the fuck not? These two 3D platformers still feel like a breath of fresh air compared to let's say, Mario or Sonic games!
Activision owns Spyro and Crash and rather than torturing them Spyro was turned to some weird defected dragon for the Skylanders series. Crash Bandicoot? Last I remember he was in a game called "Crash Mind Over Mutant" which really never felt like a true Crash Bandicoot game at all.
I in fact recently bought the Crash PS1 games and Spyro's just to play it again because there's really nothing like it on today's modern consoles (Knack is like a poor man's Crash Bandicoot, imo).
R.I.P Spyro and Crash.
