Personally, I think we have enough CKs that browse the gaming forums, and the gaming forums don't need much more supervision than they already do, and Candidate 3 already contributes to the Gaming forum as best he can. Rather, we need someone who covers more ground, and being a member of the staff will help him or her connect to the staff more, to give recommendations more directly, and have their recommendations cover a larger portion of the site. But, of course, being a CK also means you have to not be too biased towards certain people and let them go easy on obvious obstructions of the rules, so maybe everybody's friend isn't the way to go here.

I think Candidate 5 looks best.
