I’m working on a third-person shooter. I implemented almost the entire client part and I want to start making a network. As a programming language on the server, I want to use Node.js. Now I have implemented a simple logic of moving around the network, using the glitch service, but I would like to use a specialized solution. Among such solutions I found: playfab, gamesparks, app42, but I do not know what to choose? I really appreciate any opinion or advice.
