I have made a decent amount of small multiplayer games but I want to make a big one. I know how all the networking works but I need the steps for a big one. I used to just set up the server and the client right away and code all the game code on the server side while implementing multiplayer. But for a big game do I first make the single player then convert all the code to the server side to prevent hacking, or just start the code on the server side. If anyone know or has any tips please let me know.
