I finally unlocked the Ronin and Hexer classes, not that I plan to use them much. My core unit of Protecter, Landsknecht, Combat Medic (Caduceus FTW!), Survivalist, and Troubador, has yet to encounter any F.O.E. they couldn't take down. This game is crazy addictive. It takes just the very core gameplay of your typical turn-based JRPG, adds a nice character customization system, and then puts you in a long dungeon-crawl and leaves you to do the mapping yourself with the stylus. It may not sound like a lot of fun, but in practice it's great. And the story is told in first-person, as if by a DM, so there's no melodramatic latter-day FF protagonist angsty crap.
In other news, I played just long enough of GTA IV to get past that one mission I was on, and I failed once again to get past Green Grass and High Tides on hard guitar in Rock Band.
