Lincity

Lincity is a free sim game which puts the player in control of managing every aspect of a city's socio-economy. A unique feature is a choice between two ways for winning:
 * reaching sustainable development
 * evacuating the entire population with spacecraft.

Gameplay
The player develops his city by buying appropriate buildings, services and infrastructures. Player has to take care of population growth and various socio-economical balances.

The simulation considers population, number of jobs, foods, goods, raw material, services, energy and other constraints like finance, pollution and transports.

Various indicators are provided, like mini maps or statistics.

Original Lincity game
This version can be played on older computers, without a 3D graphics card, low memory and a slow processor. It features complex, 2D, top-down gameplay. It was last updated in August 2004, although any changes since 1999 have been minor.

Lincity was originally designed for Linux, but also runs on Windows, BeOS, and OS/2, as well as a huge variety of Unix-styled systems. Mac OS X, however, is only supported when compiled from source using GCC and run using X11.app. It uses SVGALib or X11 as its graphics interface API on Unix systems, with a variety of native versions on non-Unix platforms.

It is Released under GNU GPL license.

LinCity-NG
LinCity-NG is a fork Lincity with 3D graphics and new sounds. However, the gameplay is identical and it can read classic Lincity save files. It is still in active development in 2007 (new translations, bugfixes and small improvements).

It is released under the GNU General Public License with artworks dual-licensed under that and Creative Commons Attribution-Sharealike 2.0 license; and DejaVu fonts included under their own liberal license.

It uses SDL and OpenGL, and has an isometric view.

It was The Linux Game Tome Game of The Month for January 2005.
