Multiplayer resources

Hi everyone!
These days i have been investigating about serves and other systems to make a multiplayer system, but after all, I am really confused.
I have seen that the that there are some possibilities like Photon or unity multiplayer, and I would like to know which is the best option.
Also I would like to learn how it works, because I don’t know nothing. For example, making 1 vs 1 game, where every player have their owns soldiers, how can the server simulate a war between they.

Thank you for all

I’d suggest starting with some online tutorials, such as on youtube, etc, and trying to put together something simple yourself. You can do that for Photon, UNet, and other options, and see which one is the best fit for the game you’re intending to make. Think about what 3rd party services your game may need, such as the Unity Multiplayer matchmaking and relay services, while you’re doing this.
