I've got a few ideas, but like some other not-so-rich people, my own site isn't making enough money (for me anyway) to fund the other ideas waiting. And it took me a couple of years before I could start my own site. The years before that, I attempted a few forum-based games, more as an experiment.
I tried to make a provably fair poker game. The idea works. But the players didn't want to play.
I tried to make a lotto game, which lasted about a year. (Mr. RHavar, you could pick some ideas from that thread if you want.)
I've got a few more couple of ideas for casinos, that I believe would be big, but selfishly don't want to share it, hahahaha, so like that other guy, it will just be an idea in my little notebook. I'm thinking, I'll be in a better position in another couple of years to actually try it out, and I'm betting no one else has the same idea. (This is a gamble in itself. Can you imagine if you invented SatoshiDice when it started?)
And since the dawn of investable bitcoin casinos, I've found one way to make gambling provably fair for non-owner investors; at the cost of time. Slow games aren't as exciting as fast games. That's true for sports, for real life, for war, and anything that has some sort of competition.
I mean, no one wants to be a cockroach even if you could survive a nuclear bomb. No one wants to be a plant that can't move. (That's why there's a non-gambling game that has moving plants that fight against slow moving zombies, haha.)
For everyone else, if you have an idea, let me give you an idea of what it would cost to make your game. You would need to spend anywhere between 10 to 20 to 30 BTC (or fiat equivalent) to hire your coder, unless you can code it yourself. When you start out, you will need to buy a few things like your domain ($10 a year), maybe a SSL cert ($5 a year unless you want Extended Validation), and decent hosting ($50 a month for a VPS type of thing, to $100's for a dedicated server or cloud solution or gaming something.)
And then there's marketing.
On top of all that, if it's gambling, either you have to fly under the radar (or be anonymous), or you get the proper licenses, or just be able to run it with some sort of impunity or protection. (Like me, no one is going to hunt me down for my little dice game.)
Here's an experiment, can I invite the readers of this thread to look at my site? It's been out for several months, but if you have never seen it until today, then, well, that's my poor marketing skills (or maybe I really just don't have the time to spend on it like I should be doing.)
When you run a bitcoin game site, it has to be a full time job for you. It's not for me, that's why I'm not making money on it. It's like catch-22, I will run it full time if I make money, but since I'm not making money, I can't run it full time. LOL.
For you people who do have the money to try something, but don't have your own ideas, would you like to take a gamble on my ideas? I've handled money as escrow, and as part of my real life job. I just don't have my own money to do it right now. Honesty system, take my ideas, make it a website, and we'll talk. But to weed out the wannabes, I will need proof (easy, just sign a bitcoin address right?) or reputation or, something else that convinces me.
