Already saw this...
... when it was uploaded before, though I'm glad the to see that the true creator get her deserved recognition.
The graphics very silly looking. not super realistic , but that was on purpose and it really enhanced the humor, and the animation looked smooth regardless. It felt pretty fast paced, and I liked the cracks about the Player Character only getting the sword in Arsenal Gear, or the difficulty of swimming in MGS2, I think fans will really be able to appreciate that.
I cant really say much about its relation to the manga, because up to this point I think I've only heard about, it sounds familiar. I'll be sure to look into it, though. (I suppose I'd be pretty far behind in the story by now, right?)
Give it an 8 because its great, and a 5 for hilarity.
