Psp version less than half price

[dkwookie]

just checked ps store and BoP on PSP is down to £13.99. That's less than half price it was. Worth a pop at that price for some mobile action.
Not sure how it stacks up to the ps3 and 360 version.
Some other good games cheap there too. I bought a psp go last year and not played it for a bit so may stack it with some cheap games.
I can play that stealthily while the mrs watches House
