Well, while it it might not have to be an Event per we, I think it'd be nice to have a "Summer Game Night" kind of a thing, preferably on the same day each week. It'd be a great way for users to meet those whom they haven't met before.
It's my job to help the next generation, and set a good example for them. And for that I'll gladly lay down my life.
Y'know, you coul make it so Gameshow tournaments were made, and the GAMESHOW host who hosted the tournament would be able to start a celebration event for the winner of the tournament.
