Not sure an AC game suits PSP. Unless you really, really dropped the graphics down you can't have the open world, the bustling people, etc.
I wish developers would just accept some games don't work on some devices without major gameplay changes.
On PSP I think they should have dropped the open world, went with more interior driven missions (inside caves, castles, etc.) and some stealth with combat and alter the core approach to suit the capability of the device.
Try to be reasonable... its easier than you think...
