[citation][nom]john_4[/nom]The day of Windows and their proprietary Direct X monopolizing the gaming industry is almost over. OS X is now on STEAM and Linux is not far behind since both are based off UNIX it is logical and not hard to put Linux back in gaming arena.I will finally be able to drop Windows from my house once and for all and my gaming rigs will be cheaper to build since Linux is free.[/citation]
Wrong. Neither are Unix-based. Linux was created by Linus Torvalds, and was essentially a project inspired by Minix (a Unix-derivative). Mac OS X is partially Unix, I say this because it is a derivative of NextStep (Unix derivative), and BSD. BSD is a fork of Unix TSS 5, and has since been heavily modified into it's own OS family; as such it is incompatible with Unix applications, yet it shares similar features. As such, Mac OS X can be considered Unix-like; compatible to some extent, but not 'pure' Unix. The two major 'pure' Unix OSes are HP-UX and OpenServer 6.x. However, you are right with Valve's progress on porting to Linux. The Steam Client is being ported, as well as the version of the Source engine that shipped with Left 4 Dead 2 (as is evidenced by Phoronix's pictures and video of L4D2 running on an Ubuntu workstation). The results of the Source/Steam's port remain to be seen.
