Which psp game is the longest with the best replay value??daxter,God of war:(both the games)?

add these games too:syphon filter dark mirror and logans shadow , jak and daxter lost frontier,resistance retribution,lego batman,JLA heroes,MGS portable ops,ratchet and clank size matters,secret agent clank...also does these games have game sharing and by replay value i don't mean running around searching 4 stuff but 2 play the game again....(ps feel free 2 add ur own suggestions i really want a good long game and i am a hardcore gamer so sum games end up too short 4 me)
