how do i make a videogame

hey /prog/ramming, can you help me on making a videogame? i want to make a videogame to play. the graphics dont have to be good they can be like nintendo 64 graphics. it will be like skyrim but where to you can type talk to all the npcs, and theyll remember everything you say and can talk to you normally. also there wont be a story but the map goes on forever like in minecraft.

thanks

Pretty interesting, >>12
