I'd like to see something like this take hold in the CoD community:
The first Saturday of every month is a day where everyone understands that we're all going to play whichever past CoD we liked the most. If this was widely accepted I think we'd still get some enjoyment out of old games, and there'd be at least one day a month where you could find unhacked lobbies in old CoD games.
So, what does everyone think? First Saturday of the month sound good? March 3rd is two weeks away. Spread the word and go play your favorite old CoD title that day.
