I sunk multiple 80+ hour play through's on the original for the PS one, so when I heard they were re-releasing it on the PSP with added content and multiplayer I was sold. I actually got a PSP specifically to play this game. My room mate at the time also got it and we spent way too many hours playing the co-op missions over and over again trying to get the new gear that only drops from the new missions. The new content is actually really fun and really challenging. I just wish the PSP let you play over the internet so I could play this more often with other people.
