Julius is a city-building game that is an open source re-implementation of Caesar III.
The project recreates the original Caesar III game logic faithfully while adding modern platform support and quality-of-life improvements. Julius requires the original Caesar III game files to run, which can be obtained from digital storefronts or original CD-ROM versions. The tool maintains 100% save game compatibility with the original game, meaning saved games can be freely exchanged between Julius and Caesar III. The implementation deliberately preserves gameplay bugs present in the original to ensure this compatibility. Enhancements include support for widescreen resolutions, windowed mode on 32-bit desktops, in-game quality of life improvements, and support for high-quality MP3 music files.
Julius suits players who want to experience Caesar III on modern platforms and operating systems while maintaining the exact vanilla gameplay and feel of the original. The project explicitly distinguishes itself from Augustus, a fork that implements gameplay changes such as roadblocks; choose Julius for a faithful experience with visual improvements, or Augustus if you want modified gameplay mechanics. The tool runs on Windows, Linux, macOS, PlayStation Vita, Nintendo Switch, Android, and web browsers via Emscripten, making it accessible across a wide range of devices.
Development activity shows consistent engagement with the community through an active Discord server. The project maintains clear documentation including build instructions, running guides, and detailed lists of both improvements and preserved bugs.
