The Labirynth is vast and endless. Good thing you have your map!
New equipment becomes available after certain missions you receive from the Guild--A group of adventurers trained to protect the Etrian world--and game play is fairly smooth.
The only thing that keeps this game for reaching the top is the amount of level grinding(some monsters can be defeated only after training up about 10 levels) and the battles are repetitive as well.
As long as you're prepared to spend a good while perfecting your five-man team, you'll love this game.
The good-Graphics, customizable characters. hours of game play and missions
The bad-Difference of levels/strength between you and monsters. Graphics are pretty basic, nothing incredibly flashy.
