Firebase as a multiplayer platform

For many developers, using a cloud-based real-time database may be way out there and not even worth consideration. Of course, it also very much depends on the type of game you are developing. You likely wouldn't want to use a real-time database for a FPS, but fortunately, Unity has excellent options for that. For a location-based game, though, a real-time database makes ideal sense for all the reasons we mentioned earlier.
