For commercial game software, Andrew is certainly right that one it  
more likely to be able to run Linux versions.  However, something  
like BZFlag runs on both MacOS X and FreeBSD, as do almost all of the  
Roguelike games (URogue, NetHack, Moria, Angband), and many other  
Open Source games.  Felix, try looking under /usr/ports/games....

At the time MacOS X was first released, the majority of CVS tags in  
the kernel and library trees came from NetBSD, with FreeBSD being the  
second most common.  At the present time, from http:// 
developer.apple.com/technotes/tn2002/tn2071.html:

"Evolution of Mac OS X

Berkeley Software Distribution (BSD): Part of the history of Mac OS X  
goes back to Berkeley Software Distributions (BSD) UNIX of the early  
seventies.  Specifically, Mac OS X is based in part on BSD 4.4 Lite.   
On a system level, many of the design decisions are made to align  
with BSD-style UNIX systems.  Most libraries and utilities are from  
FreeBSD, but some are derived from NetBSD.  For future development,  
Mac OS X has adopted FreeBSD as a reference code base for BSD  
technology. Work is ongoing to synchronize all BSD tools and  
libraries more closely with the FreeBSD-stable branch.

Mach: Although Mac OS X must credit BSD for most of the underlying  
levels of the operating system, Mac OS X also owes a major debt to  
Mach.  The kernel is heavily influenced in its design philosophy by  
Carnegie Mellon's Mach project.  The kernel is not a pure micro- 
kernel implementation, since the address space is shared with the BSD  
portion of the kernel and the I/O Kit."
