Need Writer For RPG Thread

Hi, I'm looking for help writing an RPG. I need help with stuff like character races, classes, skills, etc. I'm thinking it will be like Minecraft/Skyrim/Cube World, though I haven't decided yet. I will be programming all, or at least most of the game by myself and will worry about graphics later. This will be non-paid work, unless the game makes money. My skype is harshicly5. Also, I'm 16, if age matters to you.
