Query: Demon stone is 5 stars.

Demon star is a good game if you like magic concepts. If not, this game will be a highly new change for you. If you have absolutely no interest in magic, combat, and RPG's, do not play this game. It has great graphics, good handling, and so on and so forth. The game is a good game if you like RPG adventure games.
