I'd like to see a return of the original invisible man event, that one, alongside jail night (for obvious reasons) was my favorite. I side with Ric on a little bit more mic control, it is nice for everyone to be able to use their mic, but a lot of the time it usually ends up with a lot of people talking over each other, and generally being chaotic and annoying :/.
Edit: Attended the last dodge-ball night, that one was a lot of fun as well!
