Currently I am searching for a btc game idea. Ideally the game will be browser based, multiplayer, 1v1. As an example you can take the classic Tic Tac Toe game, user A vs user B - who wins takes the stake (the stake would be the gathered played amount).
I am going to put on the table $2500 (in btc) or even more for the best game idea.
I think the people need a game which is Mafia-based. Maybe more real like second life. And a little bit virtual reallity.
Well, to explain you more send me the $2.500 and you just have to wait some time --- you will understand the biggest idea how to make money. At least $2.500.
And its real time + amazing real. And I even have a proof-of-concept for you in my wallet (around $2.500)
I bet every member will love your game, if you stay the game master - big daddy
