Good news to old time gamers, now you can play Dune 2 on Linux operating system natively (without dosbox or other emulator) with Dune Legacy project. For the uninitiated, (to my best knowledge), Dune 2 is the first RTS game for DOS (by Westwood, then acquired by EA Games) that spawn several other popular games in the genre such as C&C, Red Alert, Red Alert 2, etc.
Youtube video of Dune Legacy :
The Ubuntu binary (playable under Lucid Lynx) is available from – http://www.myway.de/richieland/dunelegacy_0.96_i386.deb and http://www.myway.de/richieland/dunelegacy_0.96_amd64.deb
Naturally you would need the original data files and maps to play Dune Legacy natively on Linux. Binaries for other operating systems (Windows, Mac OS X) are also available from the Dune Legacy Project website.
