The chatbox could be a place where there are random phrases thrown around, with some useful information hidden somewhere. You could even take funny quotes from the archive, even the naked act you performed :tongue:. Now that was funny.
In my opinion, the enemy should be ESA related :P
Also, there could be puzzles related to known and old bugs of the site, including the infamous "missing country" bug.
And there should be a puzzle that teaches people that they should try old games with DOSBox
Well, this is a little brainstorm. Maybe later I could develop them in a more useful way...
