In 2008, the PlayStation 3 received firmware 2.40, bringing with it the Trophy system - Sony's answer to Microsoft's Achievements. The PS3 had already been out for two years, and because Trophy support was not made mandatory until 2009, developers did not need to patch legacy titles to incorporate the new reward system.
Next month, Metal Gear Solid 4 will finally receive a Trophy patch, fulfilling a request players have had for years. Nevertheless, some of the PS3's best titles still lack Trophy support, and we've got the five most notable listed here. So sit back, and cross your fingers that these games may someday receive a patch.
