All you have is a WWIII first person shooter–which means nothing, what is the game like? What makes it unique? Why should people be interested in your game?
You don’t have enough time to learn how to do all of those things well, no one does, people spend years trying to be good at one of those things. While sometimes people think they are willing to spend the years learning and working on the game to get it done eventually, the reality is that it’s always harder than you think. It’s likely that in that time you’ll change your mind about the project or get interested in something else, or you’ll realize how much work there is and that it would take too long to do.
