 ### Development History
 
-_Dune Dynasty_ was initially developed by __David Wang__, with the source code hosted on [SourceForge](https://sourceforge.net/projects/dunedynasty/). Its last official version was v1.5.7 from 2013. After that __David Wang__ added lots of new features (mainly multiplayer) up until 2015, but never released a new version. Later some github-repos emerged with additional fixes and improvements (by [1oom-fork](https://github.com/1oom-fork) and [neg3ntropy](https://github.com/neg3ntropy/dunedynasty)), but again no new release. This fork is intended to merge these improvements, fix further bugs, add minor features, and provide new releases (v1.6.0+) with binary download-packages for Windows and Linux (see [this fork](https://github.com/YuriyGuts/dunedynasty-macos) for Mac).

 _Dune Dynasty_'s unique selling points are probably it's faithfulness to the look and feel of the original (due to it basing on an [engine re-creation](https://github.com/OpenDUNE/OpenDUNE) of the original) combined with many control modernizations, it's support for [fan-generated campaigns](#custom-campaigns), [various music soundtracks](#external-music-sets) and multiplayer.
