Adding Players to Your Game: Design & Implementation Guide

To help you add multiplayer, I need your game context. Answer these:

1. Game Type & Platform

• Video game? (Unity, Unreal, Godot, GameMaker, custom engine, web)
• Board / Card / TTRPG? (Physical, Tabletop Simulator, Roll20)
• Mobile? (iOS/Android, native / Flutter / React Native)

2. Current Architecture

• Single-player only? Local multiplayer (shared screen / split-screen / pass-and-play)?
• Networked? (Peer-to-peer, client-server, relay, dedicated server)
• Turn-based or real-time?

3. Player Mechanics

• What does a player do? (Move, shoot, build, vote, trade, roleplay)
• Shared state? (World, score, turn order, deck, economy)
• Max players target?

4. Goal

• Co-op? Competitive? Asymmetric? Social deduction? MMO-lite?

Based on Answers, I Can Guide:

• Design: State replication, authority, latency compensation, join-in-progress, host migration.
• Engine-Specific: Unity Netcode for GameObjects / Photon / Mirror / FishNet; Unreal GAS / Replication Graph; Godot Multiplayer API / Nakama / ENet.
• Backend: Steam P2P, Epic OSS, Photon Cloud, PlayFab, GameSparks, custom (Node/Go/Rust + WebSocket/UDP).
• UX: Lobby, matchmaking, invite codes, cross-play, voice/chat integration.
