Just go to the classifieds section and find 3D artists/a team, and start making a game.

So little trade secret coming your way.

Fun games are still fun if they're being played with cubes.

It boils down to game play. Pure and simple. If you take a game like Worms. A game that has been around for ages and replace the terrain with plain green voxels and the characters (the worms) with little pink cubes, it would still be fun to play.

Now take a more complex game like Grand Theft Auto 4. Really pretty game with lots of complex elements. Well, if you boil it down to cubes rendered out in a massive cube city with pretty shading and lighting and weather effects, you still have a fun game being played in a beautiful engine. Again, lets look at another game in the same vein that didn't do as well, Sleeping Dogs. Sandbox game with tons of interesting elements, in depth story, and beautiful graphics. It didn't do as well. Why is that? Because its elements weren't as polished as Grand Theft Auto 4's. It was repetitive and lack luster at times. And more so, if you played it with cubes, it wouldn't be all that fun.

All I'm saying is any great game idea can be made with incredibly basic graphics and still be great, so please stop insisting that you need piles of money to make your games.

You're doing you and your game ideas a disservice by adding those financial limits.
