The reason i say that you should rent it and not buy it is because it was very short. I realized that it was lacking after i started feeling that the game was almost over after my first 4 hours of playing in the day. The storyline was great and the characters were well developed, but it just isnt worth $40 or even $20 for that matter. The gameplay was awesome!, but it just didn't last as long as i expected, so if you want to play Ys:The Ark of Napishtim, than you short just rent it, and you'll later notice that you would have lost a lot of money if you spent $20 or $40 on it.
