Valkyria Chronicles is a TRPG, where you command a squadron of soldiers in a war between two empires.
Pro Great turn-based, tactical gameplay
Valkyria Chronicles features an expertly-crafted, turn-based combat system, where you control only a few characters in each battle. You are often against greater numbers, so tactics play a huge part in this game.
The combat system is called BLiTZ (Battle of Live Tactical Zones). You view an overhead map of the combat area and can control each character individually. There are a plethora of options with each character: repositioning to have a better attack capability, taking cover, using special abilities or items, or simply attacking. These actions are limited by the AP gauge, so you'll have to pay close attention to how much you can do in a single turn.
Each character also has their own class, so you'll also have to plan around their strengths and weaknesses. Some are better at moving, some are better at shooting, but most of them are defined by their special abilities and stat modifiers.
Pro Amazing soundtrack
This game features a soundtrack composed by Hitoshi Sakamoto (known for his work on FFT and FFXII). The orchestra music makes you feel various emotions at the right times. It's a mix of melancholy, hope, and also fear. Some of the songs make you feel even more tense than the battles themselves.
