I haven't played a Xenoblade before so can't say for sure if I'll hate it, but so far I hated all games that feature such a menu-based/mmo-like combat system, so it's a easy assumption that I'll hate this too. Other than that a lot of things look really hit or miss for me. Some combat moves look really cool, but outside combat the animation of the characters look very stale and emotionless. There are some good looking armors, but a lot of characters themselves just look awful to me. Most areas look great, but there seems to be a fine line between unique and generic. The music is very hit or miss, some sound very atmospheric even with lyrics but others are bad enough to probably make me mute the tv.
Most of this are just small dislikes though, things that I will either grow on me or bother the crap out of me depending on how much I like the gameplay. There's the problem right there, I have no idea if I will like it because I'm not familiar with Xenoblade's gameplay. I do know that small things like I said do always add up, so it's definitely gonna be a case of really loving it or really hating it. I'm just gonna dive blind into the n3ds version and hope all my questions will be answered there.
