@d3x0r,all
  In my opinion actually making the game is the hard part. Building assets as an indie developer is a lot of work. If you obsess about perfection and consistency overall you have to do everything by your own hand. That means that I do the mechanics & research, tuning, level design, visual art, sound effects, story etc.

  On the other hand I want to see open doors self-emerging online communities beat corporations in the business game. Normally, this means that the community is sustainable and makes money.

On a more lighter tone I did find this on steam: http://store.steampowered.com/app/290060/

  What got me interested in Blackvoxel is the code and the mechanics. The code can be kept under control and reasoned about by a single person. I fully congratulate the owners for their skill and experience. The mechanics... even one of those mechanics can make a game: http://www.zachtronics.com/tis-100/. On the other hand it requires a tremendous amount of tuning and personal investment. In reality a successful game can be done with much less runtime logic and better assets and design.

  Finally I want to say that I actually ditched 3D and multiple mechanics totally. I am building a 2D pixel art game with a single mechanic. The mechanic is original as I didn't see it in another game and it as a lot of content potential. The engine is written in C & JS and compiled for the PNACL platform. PNACL is the precursor to web assembly. The real-time logic is done in C and the user interface is in HTML, JS and CSS.

I want to use Blackvoxel to build a commercial game. My plan is to keep private artwork(sounds & textures) and level design(including interpreted MVI behaviors). On success I plan to open bug bounties to give back to the community. Are you ok with this? please correct me if anything is incompatible with your views or GPLv3.

The game will be a puzzle platform around all kind of processes. Some mechanics:
- Solve magic squares to open doors under a time limit. You may solve the first by hand but under a constrained time limit or a bigger square you need to instruct your MVIs(molecular voxel interactors) to help.
- Build in parallel with your MVIs from blueprints
- Navigate mazes with MVIs to get the treasure
- etc. (in the works)

Do you see yourself playing such a game? I don't really like puzzle games. They are slow and you don't really learn anything from them. This game is more about personal development. To build your knowledge with pleasure.
