Should I play MGS4 if I've never played any of the other MGS games?

[Gilgamesh]

Well I guess I'll have to play the first three games, I'm not to big on watching trailers or reading summaries about the first three so I think I'll just play them just to make the MGS4 experience that much better. (But it's going to take me forever to get and beat the first three MGS games )
