To be blunt, who cares? Honestly, that's great that he's managed to create a solid looking alpha for his Dragonball game in such a short time. I'm not sure how much experience he has with coding or game development in general but his creation is no doubt impressive. With that being said, what he's working on also seems to be a solo project and I would argue that it's easier to set your own pace for something that you're working with nobody else on. When it comes down to ESF, I would imagine that it's hard to get a team of ~10 people to meet deadlines and commit more than ideal work hours on a project that is being worked on for fun in their spare time when they have real life commitments such as school, wives, kids, jobs, and other stuff. It all just simply boils down to it being two different development situations for two different games.
