Do you mean the set that comes with Shooting Love 200X and Shooting Love 10th Anniversary?
Just a quick note, only Shooting Love 10th Anniversary was region free; Shooting Love 200X was region locked. Someone over on the system11 forums emailed Triangle service
asking about this, and got a reply that 200X is still region locked. So this collection has one region locked disc and one region free disc.
I already have both (playing on a Japanese 360), so I don't plan on picking up the collection. But if you have any questions about the games I can try to answer them.
