Haven't played Freedom Wars but I've heard great things about it from my friends who share the same tastes. P4G on Vita is the definitive version of what was already an amazing game. If you haven't played any of the SMT games, well, it's a great one to start with. Superb artwork, stellar character development and interactions, a top tier soundtrack and many, many hours of fun and interesting gameplay. Can't go wrong, especially for the $20 the game costs now.
