I have been playing the ever living hell out of this game, just wandering around areas, killing stuff and collecting loots. The battle system is nice and the graphics are some of the best I've yet seen on the Wii. The music is amazing too and is catchy, I've not yet gotten tired of any of the bgm while hanging in an area for while.
I've found myself comparing combat situations with mmo games though, since you need to be careful of where you are fighting mobs or you will aggro adjacent groups, which is usually a party wipe. And you have to watch for knock backs when fighting on a cliff, or you will be thrown off.
One thing I still can't seem to get the hang of is the Monado's future sight ability and warning party members/ preventing abilities in time. I may need to reread that tutorial.
But yeah, this game is brilliant. So glad I snagged a copy new, and didn't wait to hop on the bus. Play it.
