if for no other reason you should buy one to become part of the most obnoxious fanbase ive ever seen..
as the others have already pointed out the number of rgps is rather small at the moment... folklore ,valkyria chronicles disgaea 3 those i can recommend eternal sonata seems like a good choice aswell if you dont already own it for the 360... and thats pretty much it... enchanted arms and lair you could try if you can get them cheap but dont expect much of it
as for white knight chronicles i wouldnt put my hand in the fire for this one ...but its going to be a while before its avaiable in the us and europa anyway .. fallout 3 and oblivion you can also get on the 360 so there is no point to that
if for nothing else get it for valkyria chronicles .. i know i did
