A Video game idea

So I wanna make video games one day (I need to be good at coding though) and this is one of my idea from 3 years ago. It's called Akamar and It's set in a Fantasy type Japan scenario thing with clans and monks, Yokai and Oni and dragons and all that. In this world you can be many things but the top three are most admired if you choose to be a warrior. 1: Weaponist, a master of every weapon in creation, they also specialize in blacksmithing so they can make their own special weapon. 2: Physical Artisitions, people who have specialized in every form of hand to hand combat and have made their own unique style that they can choose to pass down to others, and 3: Spirituals, not many people choose this since you need a attunement to nature, a appreciation to it and it's beauty, they specialize in using nature to help fight, they use staffs to fight. The main Major clans are the Atamaratsu clan, they are very brutal and only produce the strongest warriors in Akamar, the Masu clan, warriors who won with pure determination, they are very difficult to defeat and can hold of a small platoon by themselves, and finally the Suya clan, those who win wars with strategic thinking and intelligence gathering, the Shogun always want them as war advisors.
