So here's a dumb question: is it a bad idea to play 4 without having finished the first one and never having played 2 or 3? I don't have a ps3 so it's not like I'm going to run out and buy this today, but I don't own 2 or 3 and don't think I'll have the time/patience to play through those just so I can enjoy 4 one day.

I know MGS is really story-centric, so I'm guessing I already know the answer to my question.
