I didn't really care for this game that much. The plot doesn't bring much to the table, it drags on too long but then is over just as it's getting interesting, you need to know to bring specific weapons for certain objectives, and it doesn't do anything that Peace Walker doesn't do better. That being said, the gameplay is a pretty decent way of bringing MGS3's gameplay to PSP, it does provide a solid base for Peace Walker to expand upon, and the sketchy comic book style of the cutscenes is a unique style choice that I'm kinda glad Peace Walker retained. I don't think I'd play this again, but I don't really regret playing it.
