I've only implemented co-op multiplayer in my games before and I've been wondering if the default networking options are safe for competitive games when there are malicious actors. For instance, can they manipulate packets sent and recieved? Do I have to do all collision checks on the server side so they can't be manipulated?
Should I just discard the idea and use Unity for competitive games?
