I just bought a 360 yesterday and I love AC so far. Visuals are fantastic and it's fun jumping and climbing all over the place. Although I agree that the fighting moves can become repetitive if you play with a "frontal assault" mentality, I think the game is quite enjoyable if you take on the assassin's role of sneaking up on people and finding ways to escape detection.
