kuligs2 pretty easy to run DB server, but im more interested how to run it inside the game itself.
Maybe I don't know much yet, but why can't a game run a DB server internally?
The thing is, I'm not making a one-off game, but a project. In which I'm going to start with a simple game, and then complicate and expand it. And in the beginning there will be one character, then two, then a dozen. At that I will use resources and json. And when it gets closer to a hundred, I will start experimenting with SQL. So these are very distant plans.
Multiplayer, or rather the ability to exchange data, I assume to do, yeah, through a single dedicated server, not directly between players. But this is an optional feature, not mandatory for the game.
