by Smeagle

ForgeClient or server, optionalMIT LicenseOpen source1.12.2

What it does

Lost Cities Squared generates ruined cities, railways and highways in a world, with buildings that hold loot and no mod spawners. It is described as a fork of the original LostCities mod, focused on fixing bugs that remained in the 1.12.2 version. Several generation profiles are included, such as a no-spawner profile, a GeoPol profile for cities with power, and an only-city profile. Biomes O' Plenty is mentioned as a companion for custom generator settings, and tile entities are placed with special handling rather than as ordinary blocks.

The only published build is Dev-4 for 1.12.2, dated 2023-12-20, which is also the first and last update. The mod is for Forge alone. Either side can run it, and neither side needs it. The code is open source under the MIT License, with public source code and an issue tracker.

Key features

  1. City and railway generation

    Cities are generated with buildings, railways and highways across the world.

  2. Loot-bearing buildings

    Buildings contain loot chests, and the no-spawner profile leaves out mod spawners.

  3. Generation profiles

    Several profiles change how cities are generated, including the GeoPol and only-city options.

  4. Special tile entity handling

    Tile entities are placed with separate logic instead of as normal blocks during generation.

Questions

Does Lost Cities Squared need a loader other than Forge?

No. The mod is published for Forge only, for Minecraft 1.12.2.

Does the server need Lost Cities Squared installed?

Not necessarily. Either side can run the mod, and neither side needs it, so it can run on the server, on the client or on both.

Which generation profile avoids mod spawners?

The no-spawner profile generates buildings with loot without mod spawners.

Is Lost Cities Squared a replacement for the original LostCities mod?

It is described as a fork of LostCities that focuses on fixing bugs in 1.12.2, so it is a related version rather than the same project.
