WoG vs Horn of the Abyss

Quick answer: Compare mod goals, installation paths, and save compatibility. Before changing game files, make a separate copy of the existing installation and savegames.

Before you begin

Heroes of Might and Magic III: In the Wake of Gods (WoG) is a fan modification of Heroes III. Installation steps depend on your base-game edition and whether you are using the older WoG 3.58f package or a newer ERA-based setup. Confirm the package's own compatibility notes before proceeding.

Step-by-step checklist

1. Identify the Heroes III installation folder and the version you already own.
2. Copy the game folder and savegames to a separate backup location.
3. Check the chosen WoG or ERA package documentation for its required base game and supported Windows versions.
4. Use a separate test installation when trying unfamiliar scripts, maps, or mods.
5. Launch the game and verify the main menu, one map, and a save/reload cycle before adding other mods.

Compatibility and troubleshooting

Compare mod goals, installation paths, and save compatibility. If something fails, test with optional mods disabled, review antivirus alerts without bypassing protection blindly, and compare the installed versions. Avoid combining packages designed for different game engines without documented compatibility.
