I liked a lot of stuff but only Ego is Ego.
For starters I give this a 7/10 because it's not bad for a Flash. In fact, it looks almost exactly like an Egoraptor flash.
However, you don't have the same flare as Ego. He goes over the top when he makes a joke and with really perfect timing. He's got a sort of "high energy over the topness voicing" that he brings back to "normal regular game voicing" all within instants. It's really funny when he says things like OKAY and OK SHUT UP and then he cuts to the next scene in an instant. To me, whenever you said the same jokes, as Snake it just felt like a lame version of Ego.
All his animation is quick to suit his voicing of the characters. This flash felt slow to suit your voicing, which I didn't enjoy.
It was funny, but as far as Metal Gear Awesome goes this definently was not up to par.
You shouldn't feel bad though because Ego's style is very hard to recreate. No matter what people say.
Your goal behind this flash might not have been to copy Ego perfect to a T but I felt like you were trying to, so that's why I have to give it 7/10
