one thing people need to be wary of though is that there's 5 chapters in the game, but the credits play after the 4th chapter and you get the normal ending and all that
but then the game continues past that with another final boss and ending that ends up giving you a better idea on why Big Boss ends up the way he does later on in the series.
Plus you get to build your own Metal Gear. Who doesn't want to do that?!
