I'd say It has potential.
DKC was alright, but kinda dragged for me. I did not sit through the entire video. It was mostly a standard review slurred, and did not have any really funny bits.
Maybe give him a co-host to bounce off of. Most let's plays tend to be funner when the host has someone to talk to instead of rambling to himself. And maybe keep the episodes shorter. Maybe record some game play when he is drunk.
Your production was good though, good camera, good mics.
Being your first video, I understand that it wont be your best. I'm starting a Let's Play channel with a friend, along with some other stiff, and our first few days of recording largely sucked. As we did it more we got more conferable in front of the microphones and got better. None of out earliest stuff is uploaded yet, There is only 1 game session from day one we may post anytime soon.
The episodes posted were recorded after a few days of "Failed sessions"
