Jackpot Idea

Iv seen alot of jackpot weekends in halo reach. This weekends is the largest i have seen being up to 39000 credits. But then i had an idea. What if there was an even larger jacpot than that. Lets say oh 500,000 or maybe larger. It doesnt matter what playlist you are playing. All you have to do is play and there is a chance you could get a 500,000 credit slot machine. Not quitting increases your chances of getting it. TO me it just that 39000 is a nice little boost but a jackpot shoulbe be something huge so please if you support this idea please share it.
