I personally didn't find this as good as most people. It's still quite enjoyable. Egoraptor hadn't even gotten a video of his own out yet! The animation is quite nice. The best part is probably where Snake mentions Otacon's twin. Some of the animation did seem a bit off.
I do enjoy this because the good definitley outweighs the bad. The jokes are pretty unexpected. I guess I just am kind of tired of these parodies. I feel so dumb for never having played any of the games. Of course I recommend it!
