Mythbusters - Is Linux hard to use?

Linux suffers a little bit of a perception problem. When most Windows or Mac users picture a Linux desktop they imagine something looking a little like this:

 
Big boring command lines and indecipherable text that only the nerdiest nerd could possibly interpret.

List of Games That'll Run on Linux

Okay, so I'm not the biggest gamer (after all, I do run Linux) and I'll be the first to admit that gaming hasn't been a strong point of Linux operating systems with most games designed to run primarily on Windows then maybe on Macs with Linux a long forgotten afterthought.

However, I've noticing things are getting steadily better in particular with the gaming platform Steam beginning to accommodate Linux users. Here's a short list of the games you can run without a hitch on a Linux OS:

Besiege
Physics-based building game where you build medieval machines to achieve tasks, level villages etc.

Counter-Strike: Source
A classic and still very popular first person shooter.

Half Life 2 & Gary's Mod 
Great first person shooter campaign (HL2) and its sandbox spin-off.

CIV:V 
Incredibly expansive and complex strategy game.

I'll add to the list when and where I find them...

Edit:

Definitely worth checking the Steam Linux store for a comprehensive list.

In addition, a whole host of Windows games are playable with the PlayOnLinux addon.
