[quote name='farley91']I'm new to Metal Gear Solid. I've never played any of the games, but have always been interested in trying them. I really want to pick this up, but I have a question before hand. How important is it to play the other 3 before this one? Does the story continue from game to game (I assume it does)?[/quote]
Yes, the story continues, and you'll be missing out on a lot by jumping right into it, unfortunately. Not only will the story be hard to follow, but you won't get certain inside jokes or callbacks, which to me have always enhanced the experience.
Fortunately, you could always pick up the MGS: Essentials for $30, if you have a BC PS3 or a PS2. It has Metal Gear Solid, MGS2: Sons of Liberty, and MGS3: Snake Eater in one boxset. The only main story games you would be missing then are Metal Gear, Metal Gear 2, and Metal Gear Solid: Portable Ops. Fortunately, the first two MG games are old and not the epics the MGS games are, so it would suffice to read the summaries that are included in the first Metal Gear Solid. As for Portable Ops, you could always read a summary online.
