Most mixers have the ability to gamble over sports numbers to make (or lose) a little chyen. While corpies can travel down to Red to partake, it feels like they should have something a little more befitting for the corporate lifestyle. So how about letting them gamble their money in the Withmore Stock Market? Buy stocks in Afterthoughts, ViriiSoma, Neotrans, or others. Then sell when the time is right, or bail out as Genetek stocks plummet after a recent office bombing on Gold. Prices could fluctuate hourly, daily, or weekly, with chances of suddenly changing at any time, or even responding to real player-driven events.
It would be an extra form of income that could reward those that pay close enough attention to the numbers. My only concern would be the possibility of it replacing the need for income from a salary job. Or maybe that's a good thing?
