Added it to the list.

Had a quick read of some reviews for Infinite Undiscovery and it scored just above average 6-7/10 scores. From the makers of Star Ocean though so might be worth a play, even with some inconsistencies mentioned in the reviews (some cut scenes are voice acted, whilst others are subtitled only... but we are used to that from previous console generation so that is definitely not something I would be annoyed too much about). Other issues mentioned include bad lip-syncing, which again doesn't bother me, having played a lot of JRPGs where the original Japanese lip-syncing is overdubbed into English so don't sync at all. Not exactly reasons alone to avoid the game. The trailers also look quite good.

Having a Google about I've found a few more I've also now added into the list.

I must say I'm a little underwhelmed by the number of exclusive titles the 360 has to offer after all these years... I actually think the PS3 looks a better system for exclusives. Also many people keep saying the 360 is the RPG system of this generation, so where are all the exclusive RPGs? Most are also available on the PS3.
