The last JRPG I've finished is FF12, which was great. Yes, the story was whatever, but I loved tweaking my gambits, doing hunts, and exploring. If I didn't have to push a button to win battles, I was pleased, but I'm a whore for strategy. I liked how the game felt like a large world and it was fun to explore and see things. FF13 just rammed me down a corridor most of the time, and had a battle system that was largely mash X, change paradigms, mash X, change, repeat. Wasn't a fan of the battle system, to say nothing of the nonsensical story and lame characters. I'd probably have liked it more if it opened up earlier in the game, but whatevs. No sweat off of my back.
FF15 looks sweet.
