I'm 40 years old and I have done this 2 times before with other engines. I can tell you that I have had many jobs and projects over the years, but nothing has ever been more difficult, yet more rewarding than designing a game and launching it to the public. To see hundreds of people running around the world you spent endless months planning and hand crafting and watching them enjoy it is the best feeling a person can have. It's the reason I'm putting myself through it again. I have a feeling this amazing engine will make things a lot easier, but I still expect challenges. You should too! You may have a long way to go but stick with it man. You will run into to endless roadblocks, it will stress you and your friends out, but at the end of the day the payoff will be worth it. I look forward to seeing what you come up with. By the way, my friend said he will definitely check your project out when it's ready. Good luck to you man.
