Arcanum was a steampunk isometric RPG made by some of the original Fallout developers (under their new company Troika Games) and released in 2001.
To help with modding the game, I made a couple of editors.
The Arcanum Dialog Editor allows easy editing of conversations in an Arcanum mod – DialogEditor103.7z.
The Arcanum Script Editor allows easy editing of Arcanum scripts – ScriptEditor100.7z.
