I'm interested in creating a (2D) battle-royale style game. I've only ever dabbled in online multiplayer before. I have a few questions: What are some things I'm going to have to deal with in GM regarding online MP compared to other engines/languages? How should I handle the server? Would it be best to have the server written in another language and only the client written in GM? What are some common pitfalls with beginners using GM networking, and how can I avoid them?
