Definitely worth the 800 pts. Stacks up pretty well to nostalgia, but worth playing if you've never tried it before.
The learning curve is mere minutes, but the replayability is forever. As for 16-bit titles are concerned, this one still stacks up well against time and other titles. The music is not overwhelming, but appropriate. The music sets a wonderful tone throughout the game and adds to full immersion.
Frankly, if you're bored and need a new game to play, this is it. And if you haven't downloaded yet, you have no excuse not to (unless you don't have the $$$ and come on, it's change!).
