Julius is a fully functional open-source adaptation of Caesar III, maintaining the original game's logic while incorporating UI enhancements. It offers cross-platform compatibility, allowing for gameplay across multiple systems. Since it retains the same logic, saved games are fully compatible, and any gameplay bugs from the original Caesar III game will also persist in Julius.

• Support for widescreen resolutions
• Windowed mode support for 32-bit systems
• A lot of small in-game quality of life improvements

Julius requires the original assets (graphics, sounds, etc) from Caesar III to run. It optionally supports the high-quality MP3 files once provided on the Sierra website.
