We are developing a multiplayer game that should be run on the local network that is disconnected from the Internet. What is the best solution to do this? Question to @Unity: will the new multiplayer system be able to support this feature (and not to count CCU)
Most networking API's support this. You're not going to get a lot of answers to "what is the best" kinds of questions, because it is unlikely anyone has had sufficient experience with all networking API's to be able to actually answer that question. Here's some of the available options. Take a look at them, figure out what looks like it will work for your project, and try a few of them out. https://forum.unity.com/threads/wha...of-available-network-solutions-assets.609088/
