The Cohhilition

Find a Multi User Dimension(Dungeon) and give it an hour or two of play time.  Everyone that wanted to join would be able to and have some fun playing.  Some of the younger viewers would be exposed to the gaming that us older folks grew up on. The games are free, the clients are free and you can have a dial-up connection and still play. 

I highly doubt this would attract anyone into watching the stream at all because it's highly boring to watch, and if the intentions were to 'educate' the younger audience it wouldn't work because again I highly doubt they'd sit through it.

I've never actually played a MUD heh. I need to sit down and really give one a try sometime.

That's probably not something I'd sit there and watch, to be entirely honest. xD
