Crash 2 N-Sane is great. The level design still holds up and is just as fun to play as it was in the original.

The jet pack levels are pretty awkward and slow but they're nowhere near as awful as the gimmick levels in 3.

Final boss is very anticlimactic and falls flat on it's face in comparison to the rest of the game, but the overall completion experience is so fun it doesn't matter.
