Because MGS is realistic right?
oh good lord not another one who says that. I don't know how many times I need to repeat this point across 100 forums, but understand that good fiction gets the balance right, and tries to be at least a bit believable even if not realistic. If your fiction has tons of absurd things which remove a person from the suspension of disbelief if it a bad fiction.
Twin Snakes took what was a workable story and turned it into a Matrix farce. Being a fiction does not mean it can get away with kicking chunks of ceiling out or jumping off missiles.
I am well aware MGS is fiction and not totally realistic, but Twin Snakes is a farce. Fact.
Good fiction works when the audience can settle into the world and ignore what isn't plausible. Bad fiction is Twin Snakes, where it is so absurd and so frequent that it does not work. This is the basics of good storytelling.
Also, bloating something is not a good thing. That's why MGS4 is so annoying, because it is a self masturbating affair. Whenever you see bloated out of control action scenes and graphics, you know it is being used as a substitute for clever storytelling, dialogue and character development. Best examples:
MGS4
Advent Children
Star Wars Prequels
matrix 2 and 3.
Final Fantasy XIII
All of these are crap. They all rely on special effects and have the most absurd bloat I have ever seen.
