First, I need to outline the structure. A good guide should cover game overview, building basics, resource management, combat strategies, units, AI opponents, multiplayer, modding (if applicable), and tips. Let me check if CODEX has mod tools or community content. Oh, wait, Stronghold games often have modding communities. Maybe the CODX version refers to a specific mod, but I'm not sure. The user might be confused, so I should focus on the general gameplay.
