World of Warcraft: 3 Open Source Clones Compared
PseuWoW and World of ClaudeCraft take opposite approaches to game data. PseuWoW needs either the original game's MPQ files or data extracted from them with its own bundled 'stuffextract' tool, and includes a debug-only model viewer; development on it is dead and it's currently unplayable. World of ClaudeCraft instead ships its own curated asset set and procedurally generates its terrain, water, weather, and towns, needing no original game files, and is actively developed with custom ruleset editing and a procedurally generated endgame 'rift' system. TrinityCore is by far the most active and largest of the three by contributor count, though the available material doesn't describe its underlying approach.
