Head Mom In Charge
It should not be on the PSP. They can make aversion of it for it, but it should not solely be on the PSP. The PSP isn't doing too well as of now, if you hadn't noticed. And the controls would be too hard. I think something should be released, but not another handheld. Maybe not another game, just something somehow that explains what's going on inbetween now and the next story.
