I completely agree with Aceio76. But I would like to add a little of my own opinions
This game engine has the potential to be the biggest on the market today. I truly believe that. But there are a few things, I feel, are preventing that from happening. I'm going to name them, just to entertain the community...lol.
And I'm going to try and find a few solutions.
1.) Problem- It is developed by one man. What if he decides to not work on the engine anymore, or something happens to him to where he can no longer work on the engine.
Solution- Hire a staff that helps you develop your game engine. If you can't afford to hire a staff, percentage of profit upon release will help you pay your employees for their work. You don't even have to pay Interns. They will work for you just to build a portfolio. Make sure you have a business license if you don't already have one. Make sure you have a written will that someone inherits your business if anything should ever happen. If whomever inherits, knows nothing about making an Engine, or game development, then it's okay...you already have a team in place. People like to see team development more. It makes them feel more secure about using an Engine.
2.) Problem- There is no Asset store.
Solution- make a store that people can submit models, plug-ins, custom anything, and it would generate excitement. People would have hope that they could possibly make a little money off of their own ideas.
3.) Problem- No Console support for Xbox or Playstation
Solution- support it
4.) Problem- No animation editor and particle editor.
Solution-bring it back. people always love more features.
5.) Problem- better documentation
Solution- Find a way to make a better documentation layout.
Even though these problems still exist, we might think its the best game engine out there, but it's convincing the rest or the world that matters. If these problems were fixed, met with real solutions, I believe the sky would be the limit for Esenthel Company, and for Greg, making it the Largest game engine company in the world that is geared toward indie development.
Maybe he doesn't want to be the largest...I don't know. Maybe he wants to keep a small tight knit community. But I Just wanted to say...the potential for large growth is there.
