I'm really interested in the title because...
First off, it looks like it's story will be "Epic". I like the huge battle's, I like the cool weapons, and just brutal weather effects :D The game's scope and style is just super appealing to me.
second off, the graphics really are awesome :D As mentioned above, I just totally dig it's immersive nature, I like that the world around you has more animation then both you and the enemies combined ^_^ I really dig it! A showpiece for sure!
The multi-player is using a class system. That's already full of win. I generally don't get into games like Halo or Call of duty because it seems like every character can do everything, and that detracts greatly from the strategy needed in my opinion. I like the strategy based gameplay as opposed to the sheer tactics run n' gun style. And class systems just rock!
