Metal Gear Solid 4 is an action packed game. Kojima put a lot of work into this game. In fact, this was probably the only game he has put so much effort into. If I were you I would play the MGS1, MGS2, and MGS3. I heard that Metal Gear Solid 3 was probably the best Metal Gear Solid 4 was amazing also. I think you will enjoy it.
