These are the mistakes (see the scores) Square has made:

The underlying assumption that good Square JRPGs do not sell well on the 360 is clouded by the fact that no blockbuster Square JRPG has been released on the 360.
As examples of a good JRPGs performance on the 360 I'd look to Lost Odyssey or Tales as a guide.
