"Hiding from your enemies?! That's not a game!"
Metal Gear Solid is a tactical stealth action series created by Hideo Kojima, you may have heard of it. It has cool characters, great action, varied gameplay, an interesting story, and it's not afraid to have a laugh at itself, or at the viewer. It's fun, it's dumb, it's got long cutscenes, it hits you in the feels, and you probably already know where you stand on the series.
Feel free to talk about the Metal Gear series here. Konami has ruined enough things in general, so if you want to discuss the current evil activities of the La Li Lu Le Lo, I would direct you to the Konami thread.
"Manwiththemachinegun, I want to play Metal Gear! Where should I start! There are a ton of games!"
You can't go wrong with either Metal Gear Solid 1, the first Playstation game, or Metal Gear Solid 3, set in the 1960s as a clear homage to Rambo and James Bond movies. Consider those your gateway drugs.

Other recommended material includes the Best Friends Play LP of Metal Gear: Revengeance, where a bunch of grown men nerd out over cyborgs in sombreros and Platinum games in general. And the Hiimdaisy, "Let's destroy!" series, a parody web comic that covered the first three games, and a bit of MGS4.
