I've only played about 20 minutes into the game so far, but I'm quite impressed. I've played Tactics and it's a great system. I think FFXII: RW has a lot of potential. Will have to see how the story unfolds to truly judge the game though. For me the story makes up a lot of an RPG but an intriguing battle system can also put the game on top.
So far the battle system is an A+. A lot of options are introduced at the beginning which show you how in depth strategy could potentially get in FFXII: RW.
It's also nice to see a new game come out. I love the remake they're doing (FFIII - FFVI), but a remake is nothing compared to a new game. Well, that is if you've already played the game. Obviously not playing a game being remade would be pretty exciting as well.
