From how I envisioned it, it shouldn't be a pure popular vote system.
For it to work, I wanted to see reasons why a game should or should not be put up on the list. I pretty much expect Coop to cover a lot of the "What the hell, I never heard of that" games and put reasons as to why they should or shouldn't be up there.
If anything, the reasons should be the main factor and not the votes themselves.
Is this list going to be perfect? Hell no. Will there be a lot of under rated games that will be given the shaft? More than likely.
If you ever find a game being given wrong treatment and have a reason why it shouldn't, say it. There are a lot of open minded people that will go and try it out if you give good reasons to.
