I have a broad question, hopefully I'll synthesize it well. I've been looking for the best way to store the standard data of my project. So far, I've found 4 possible answers to my problem: Binary files, Json files, XML files and local DB(using SQLite). While the first 2 seems to be common sense for store data, I would still need some opinions about it, instead of create a bunch of content and code in vain. The chosen option must generate files that can be editable at runtime. Already used some XML files for basic saving and watched tutorials on Json and Binary files but I'm still uncertain about what road to take. I believe DB's are a different animal, but maybe it would worth for my case.
To contextualize, my project is a sports game, so I must start to generate and store virtual players and teams. After that I need to link those virtual players at their respective teams. It happens that I would like to enable human players to edit those generated virtual players and teams attributes at runtime through some kind of editor. Furthermore, I want to enable human players to create their own virtual players and teams, so the chosen method must have scalability, so it's expected to have hundreds of teams and thousands of virtual players at some point. My target platform is PC, so file sizes and general performance isn't so critical as it could be on mobile for example.
Anyway, hopefully my doubts are clear enough. It would be cool if someone have something to say, I would like to know the best choice for my case.
PS: Already take a look at these 2 questions:
But most of it's answers have some years now and I still have doubts on this matter.
