Best and worst psp game so far

i was wondering what is the best psp game u played and why? and what is the worst psp game u played and why?

for me the best game is fft because of the great story, worst is atv blazin trails b/c it is boring

best game, crisis core, worst harry potter i didn't buy it but it is the absolute worst game i played for pspAdel4

Best would probably be Manhunt 2 for the gameplay/mood and length. Great cutscenes too.

Worst is Rainbow Six Vegas as nothing was enjoyable about that game. Even the online sucked..
