Go fuck yourselves guys.
Well that was a little harsh.. but yeah, you specifically mentioned disinterest from ponzis and other scams, so of course the spammers had to come in and post their ponzis on your thread. I can see the appeal if you get in at the beginning, but if you look at any of these active ponzi contracts running on Ethereum right now and actually look at their data (on ether.camp) you'll see that if you invest now it'll take hundreds more ether invested before you have a chance of getting paid. I don't see the appeal of waiting that long for a potential 120%-150% ROI.
Gambling games might be interesting, but only if it's a zero-sum game. If I want to play with a house edge, there's a brick-and-mortar casino about a half hour drive from here (and I quite enjoy the atmosphere of a brick-and-mortar casino, I love all the lights and sounds.. plus they have buildings to maintain and employees to pay, so I don't mind giving them their house edge when I play there).
I'd love to see more games based on the idea of a RanDAO (examples:
https://github.com/randao/randao and
https://github.com/MakerDAO/maker-darts ). I think there's potential there for the "house" to make a profit off of a zero-sum game, by also operating a "random oracle" service to sell random numbers to other contracts. Some of the fees from the oracle service could even go into the prize pool for each round, making the game better than zero-sum for the players.
edit: I think something based on maker-darts would be especially interesting, since it deals with tokens instead of ether, and as far as I can tell the plan is to eventually replace ether (as it exists now) with a precompiled token contract at address 0. For now, you can use ether as a token with a simple token proxy contract.
