The first 3D title in the METAL GEAR series pioneering a new level of stealth action with live action footage, cinematic cut scenes, and innovative gameplay.

In the original MGS, you mostly do stealth. Sneak up behind enemies and put them to sleep. Other than the boss battles where you MUST shoot, the entire game can be completed without killing a single soldier (or so they say). It's a fun thinking game when you are trying to evade detection and plotting how to sneak up behind an enemy soldier. You may like it for those parts. The boss battles? Maybe not but you can use the Nikita missiles to kill at least one boss in the game without having to shoot them frantically. It's a cinematic experience. All the other games in the series can't match the stealth based gameplay of the original.
If you get Vol. 1, you can play the VR missions which are again all about strategy/puzzle solving and less about shooting.
