PSP vs. DS

That still doesn't change the fact that you're wrong.

I think Hiji suffers from a nasty condition called personal prefference, which is very hard to cure. But he should still be able to live a meaninfull life. DS and PSP are entirily different systems so it's no surprise the PSP gets different games. You won't find a game like SOCOM or Metal gear acid on the DS.
