ScummVM is a program which allows you to run a wide variety of classic
graphical point-and-click adventure games and role-playing games,
provided you already have their data files. The clever part about this:
ScummVM just replaces the executables shipped with the game,
allowing you to play them on systems for which they were never designed!
</p>
<p xml:lang="xy">I18N: 1 of 3 paragraph of ScummVM description in *nix distributions</p>
<p>
Currently, ScummVM supports a huge library of adventures with over 250 games in total.
It supports many classics published by legendary studios like LucasArts, Sierra On-Line,
Revolution Software, Cyan, Inc. and Westwood Studios.
</p>
<p xml:lang="xy">I18N: 2 of 3 paragraph of ScummVM description in *nix distributions</p>
<p>
Next to ground-breaking titles like the Monkey Island series, Broken Sword,
Myst, Blade Runner and countless other games you will find
some really obscure adventures and truly hidden gems to explore.
