Oh, I also think the statistics for gambling should be expanded upon... Namely, the Top XX of winners, losers, amount of credits, number of bets, etc. Top 5 or 10 doesn't show very much and I'd like to see where I am compared to the top.
Thanks for all the great feedback everybody! I went ahead and started a lottery event which you can find information about on the front-page. I'm going to close this thread just so I can put up a new one in a couple days soliciting feedback on the lottery event and credits in general after I get some other features added.
