Though the other Metal Gear PSP games were pretty good, none of them reached the heights of Peace Walker, which was a full-fledged traditional entry in the franchise that bested a number of the console games. A good-looking stealth-action campaign, slick production values, and well-honed gameplay made it an essential purchase for the PSP. It was arguably the best PSP game ever made. With fascinating gameplay systems, a spectacular soundtrack, and some of the best boss fights in the series to date, Peace Walker stood out at launch and remains a wonderful experience today.
