Most of the games on the list are not RPGs. The battle system must resemble the old pen-and-paper RPG system.The best one would be Xenosaga, which isn't on the list.
I would buy it if I had more than enough money. It's the cheapest blu-ray disk player I've seen.I usually wait about a year or two before buying a system. For a healthy amount of games to choose from, and the dropped prices.
