Are weapons going to be working client-side or server-side? This leaves room for a ton of discussion.... especially if PVP is involved and netcode and stuff. As I understood it, the server-side bullet physics meant that your skill mattered. A shot was a shot and where you aimed mattered. It also was a more fair battle with PVP as far as I'm aware? Also lots of questions about how the AI is going to be running and what UE4 is capable of? I can only judge it based on FireFall but I don't know if the AI running server-side actually benefited the game at all. People were always complaining about rubberbanding and non-responsive AI which affected the combat. There's pros and cons to both of these options. It's also hard to separate the AI from the combat too since they go together. Since I'm not a developer, I'll leave this thread to those that know. Perhaps they can share some knowledge.
