PSP Saviour

I am currently in an undisclosed location taking part in some research for a PhD student related to sleep.
As such I have needed to fill an hours worth of time each night with something I can do in minimal lighting.
I am happy to report that this time has been well spent and I have now completed Assassin's Creed: Bloodlines for PSP. All that is left is to sync this with Assassin's Creed 2 and I will have played that game to death and have collected all that I possibly can within it.
Now however I need to find a new game to entertain myself with 3 nights next week.
