Crystalis was one of the most popular RPGs ever for the NES. The gameplay is similar to Secret Of Mana games. Which was very unique for it's time, although the game was incredibly short [I beat it in about 3 days on my first try], it still kept you busy because of the mazes and bosses, which will keep the average player from beating it in three days [I only beat it that quick because I had Nintendo Poweer to help me out]. The game was rereleased exactly 10 years after it was originally released, however this time it was released onto Game Boy Color, rather than just the NES like it originally was. Despite it's short length and crappy ending the game is still worth playing, espcially if you like Action RPGs [like Secret of Mana].
