Unique!
The problem with this game is maybe it is a bit too long and some quests later on are very tedious. It doesn't help that the story is not very interesting and the voice acting and the script are very bad. The gameplay is easy and fun, but it becomes repetitive sooner or later, especially when you have to go back and forth.
Yes, you will get bored of it about 2/3 into the game, but you will have fun for at least 15 hours with this unique budget game.
