The project looks like it is done in a waterfall model. The development travels in a linear progression where the next phase begins once the previous phase is complete (tml, alpha, beta, tau and agoras market). The advantage of this type of model is that it would provide quality, reliability and maintainability to the project. In contrast, it's a long walk for something tangible to appear. This would probably be the best development cycle choice category since the project is very complex and has a huge impact to humanity.
