Rank the Metal Gear Games
1. Metal Gear Solid - Had pretty much everything you cuould ask from an MG game. Deep story, moving characters, plot twists, awesome environments and boss battles, music...it had it all. Also had my favorit eending in the series.
2. Metal Gear Solid 2: Sons of Liberty - Often attacked for starring Raiden and its plot that requires one to think. No doubt you have to be into the story to appreciate this game but as I do love the story of the series, I love this game. The areas outside the Big Shell were gorgeous and I generally liked the new characters (Solidus and Vamp mostly though)
3. Metal Gear 2: Solid Snake - Played it with my copy of Subsistence. It had many of the elements that made MGS1 so amazing. It's cast of characters and the story told throughout the game was awesome. All culminating in Big Boss' speech of his war-controlled vision of the world.
4. Metal Gear Solid 3: Snake Eater - To contrast with MGS2's twists and turns, MGS3 was probably amde to be very simplistic. There were no scenes that made you scratch your head (except when the giant flaming head came after you i guess) but it still told a deep story of how Big Boss became Big Boss. I also loved the underlying James Bond vibe they gave it.
5. Metal Gear - A fun game but lacking the storyheavy depth of its sequels. I sitll enjoyed it.
6. Metal Gear Solid 4: Guns of the Patriots - Lacking a thick story actually beats this tripe. Meryl marrying a character who originally had no place in the series other than as a comedic foil who shit himself all the time? Talk about kicking in the face the epic ending of MGS1.
Never played PO.
