Fighting demons turn-based-style has never been so satisfying.
The game features a menu based navigation system where you can choose where to go next. Some of the locations you can choose from will feature a clock icon. This icon indicates that it will consume 30 minutes from the in-game time. Seems harmless the first days, but it will be de deciding factor when you have to choose between two events. This also means that you might be missing out on what would have happened if you choose the other event. This instantly boosts the replay value of this great game.
The characters in this game also got hold of COMP's that bears a striking resemblance to a DS system. With these comps, your characters are able to perform various tasks. This includes being able to summon demons by forming a contract with them.
At the start of a battle you'll get a brief look at the objectives which usually revolves around defeating your enemies and/or saving regular citizens. Then you'll have the option to edit your team, crack a skill, choose your characters positions and dispatch them. Each team consists of 1 human character and 1 demon on each side (3 in a team).
At the start of a mission, character is also given the option to crack (steal) a skill of the enemy. After the skill is cracked, you can assign it to any member of the group if they have the necessary stats.
Once per turn you are able to move a certain amount of blocks. You can also summon a demon from your COMP to replace one in your team.
There's also the option to attack an enemy that's near you. After you choose attack, you'll enter in first person mode. In this mode you can see the other team and their weaknesses. If the leader (the guy in the middle) dies, the whole team is automatically defeated. Each character has certain weaknesses/ resistances or immunities to certain elements.
The game also features an action system where you can bid on demons to add to your collection. The currency they use to buy demons is Macca. You earn Macca each time you defeat an enemy and also at the end of each mission.
Later in your adventures, you'll be able to fuse certain demons with each other to create new and powerful demons. It's very easy to use and you'll get a clear explanation about what you're making. You can also choose which skills they'll inherit. You'll spend a lot of time with this alone.
The graphics of this game are not bad for a DS game but they could have gotten some fine tuning around the edges. The skills are slightly animated. The game also features real pictures of various locations around Tokyo.
To conclude, this is a great RPG. However, half way through your adventures you might have to do some level grinding to stay on par with the enemies. Also, the game might get confusing at first since the game has a lot of stuff you have to remember. The game has a very immerse story, great presentation, decent soundtrack and lots of replay values due to the different endings and fusing of monsters. So overall, it's a great game.
