Dragon Quest III is a RPG that is the 3rd game in the series. It is a SNES version of the GBC version of it. I have played the GBC version and compared it to this version. I can say that the SNES version is a bit better that the GBC version. I think of it as a good game to play for Dragon Quest fans.
Graphics: The graphics in this version are better that the GBC version mostly for how they are a bit smoother. The background is great and I like how it has a background in the battle scenes as opposed to a blank white space in the other version. The characters and animation are better and more pleasing to look at. I say the graphics are good for this system.
Sound: I like the sound for how it is smoother in this version than the GBC version. (Even on this site the sound is smooth.) Not to mention that there is some catchy and memorable music in it as well.
Addictiveness: The addictiveness would depend on whether you like turn based or not. If yes than it will be very addictive. If no than you will lose interest quickly at the beginning of the game. So it is addictive to those RPG fans.
Story: Like in most RPG the story is to save the world from an evil threat. But even so it is still good. The story is where you are the son of the hero Ortega and after his death you must carry on his task of stopping the evil that threatens your world. This results in you traveling all over the world.
Depth: This game has certain features that keep it interesting. One is the class system you can also change the class one the character has a Level 20 proficiency in that class (so I've read). Another feature is the Game Towers (at least that's what I call them) there you can select one character from your party to explore a board game to receive a fabulous prize. Keep in mind that there are traps on the board so go with a character with good stats and high luck (you'll need it in the towers). A third is the monster fights where monsters are pit against one another, there you can bet on which monster you think will win, choose the right one and you earn money, player can do this as much as they like. Keep in mind If you pick the wrong monster then you will lose the money you had bet on the losing monster. So it has features to keep people playing even if they beat the main story.
Difficulty: The game can be quite difficult if not prepared right (like in most RPG) so it is good for those who like a challenge.
Overall it is a good game for those who are into RPG with its features and story fans will be hooked on it for sure.
