Pros:
-Entertaining commentary
-You're enthusiastic for the most part contrary to 95% of the other new youtubers
-Having partners always make the video more entertaining (at least in my opinion)
Cons:
-Content is pretty unoriginal, ie: minigames, advertising server, etc.
I left a suggestion for your friend smithy but I'll leave the same suggestion for a video idea here.
Take 2-4 teams of 2-4 players and give the groups 5-10 hours or so to create high-tech armor and weapons from scratch. Once the timer is up, allow the teams to fight to the death in the open area and see who comes out victorious.
And uh, if you're ever short on people to record with, wink wink.
Other than that, I think you've got a solid start for your channel.
Edit: Might want to check your channel banner, you have a slight spelling error there.
