Kartia is a strategy/RPG very similar to FF Tactics.
The plot is excellent with a story much like any other RPG (to me, that makes it rather boring). However, it changes quickly to a mystery.
This game is not as good as Tactics, but it still may be worth playing if you like strategy/RPGs. There are numerous quests, so you may need to play the game twice just to grasp the entire concept. Again, if you are impatient and get frustrated easily, this game is not for you.
