Japanese are starting to make HD version of some PSP and PS2 titles. The first game that I heard that was converted to HD is the Monster Hunter Portable 3rd Remaster edition and now Metal Gear Solid from the past. When I got my PS3 I tried to play the MGS 4: Guns of the Patriot which is the first and only Metal Gear that I played. The game really impressed me, the story line, game mechanics and cut scenes are awesome.
Metal Gear Solid HD Collection offers a handful of the most popular Metal Gear Solid titles in true HD, featuring 3 full games, Metal Gear Solid 2: Sons of Liberty(PS2), Metal Gear Solid: Snake Eater(PS2) and Metal Gear Solid: Peace Walker(PSP). They created the HD version to offers old and new gamer a chance to experience the story and gameplay of the MGS franchise.
The MGS series is also known for its storyline, which blends seamlessly with the gameplay. The scenarios are based on the extensive research and incorporate drama of actual developments in society. These elements have made MGS what it is today.
