Open Source RTS god game. Fight through ten different ages.
If you are expecting a casual game to pick up straight away, this game is not for you :) Like most RTS games, some time reading the instructions is advised. Please see the website (linked below), or click Online Help from within the game. There are also some tutorials to play through.
A resolution of at least 800x480 is recommended.
Also available for Windows, OS X, Linux, AROS.
Gigalomania is Open Source, and uses graphics/sound/music from 3rd party Free sources; see the web page for source code, and a full list of credits/licences.
Please contact me if you encounter any problems, or have any suggestions for improvements - either email, or post at http://sourceforge.net/p/gigalomania/discussion/ .
