Nice, I finished the N-sane trilogy around spring last year, but I also used to play the originals as a child.
The first one is by far the most difficult, but I'd say the third also had some really annoying levels, especially the motor bike races... my favourite one is definitely part 2 though, has the best atmosphere!
Can't believe I actually managed to get all the Gold Relics for part 3 back on the PS1, nowadays I just couldn't be bothered..
Are you going to get the new Crash game? I'm pretty hyped for it tbh!
