Got 120%. I've never played a Spyro game before.
This was a very pleasant surprise. Considering the type of game it is (3D platformer/collectathon), I really didn't expect to like it. The worlds were just the right size and (except for one world) the rather hidden items weren't ridiculous to find. Except for Tree Tops, I liked every world.
A few things kept this from being a 10/10:
Supercharge jump -- I really disliked this
The flying worlds -- but at least they didn't require near perfect execution to get through
The end boss simply being a long chase
I don't know if it was my disc (which was pretty scratched up), but on my PS3, in Toasty, the PS3 kept repeatedly accessing the CD (like it was starting to load up something), causing the music to be extremely choppy and restarting every 5 seconds or so. It had no other gameplay issues there, but I just couldn't take it and restarted on my PS2 (luckily, this was only about 1 hour in). On my PS2 there were a few places where the music would stutter for a while before finally playing with no issues, and I fully attribute that to my game disc.
