Crash Bandicoot - ...

While the First game is definitely brutal in its later levels, it never feels impossible to overcome. The N Sane version made it easier in some parts, harder in others, but it's still fun the whole way through. Haven't beaten the second and third games yet, might update this comment when I do.

I hope they'll could do Crash Twinsanity justice. Seriously, when I read what was ultimately cut form the game, I wept.
