You start in your grandpa's house, at the very beginning you will be very weak and must follow your grandpa's instructions, until you reach level 3 and get permission to leave his house and start your adventure. On the World map you will be able to visit different locations for various purposes, to rest, shop, fight, do sidekick missions and main story-line missions.The World map is shown on the picture below, blue dots are friendly places, and red dots are hostile ones, with a bunch of enemies to fight.
Battle mechanics are very similar to earlier mentioned Final Fantasy Tactics, on the start your party and enemies are placed on the two different sides of battlefield. Every character can move, perform different actions (like attacking, casting spells and using various items), end turn and view unit status. After moving or ending turn you need to choose which direction will face your character, always try to face your opponents and never expose your back to them. After killing an opponent, often his body will disappear and drop the treasure box, to collect it stand on that field with one of your characters, and after battle use your lock-picking skills to open treasure box.
