there is none because it's only idea for now. that's why he's gathering a team - to create that game from scratch.
i wanted to know if you are beginner cause there is a lot posts like "I have a super cool idea for some game, i'm looking for a team and i will be the boss, you'll create the whole game for me" type and i thought look, here's another one, but i think i was wrong. you said you have experience, and 2-3 games already published - that's good.
but i think people would like to hear little more about your idea, concept, how do you plan for that game to look like?
good luck with that game btw
