Freeware games

Free games for your PC, try all of them at least once! There's absolutely no reason not to.

This list is not for shareware or "abandonware" titles, but for games that are genuinely free so you can be both a cheapass and a righteous snob about it.

As more MMO Games go free-to-play, they are technically "freeware," but they're pretty specific, and you can't play them anymore if the company servers go away. These recommendations are for games that are free and are for single-player or LAN parties.

Download links for each can be found in the Description. {C}The type column will be one of the following:
 * .exe : available as an executable for Windows (or windows emulator)
 * .dmg : available as a package for Mac OSX
 * .tgz : available as source or package for Linux
 * .swf : Shockwave flash; play in a webpage, or download it and play off your harddrive
 * .jar : You need a Java virtual machine, might run on your smartphone too
 * DOS: Runs on DOS and anything that has DOSBox (BeOS, Linux, Mac OS X, OS/2, and Windows)
 * steam : freebie from Valve via the Steam online store
