#30 Command & Conquer: Tiberian Sun + Firestorm Expansion
Tiberian Sun is regarded by many as one of the best real-time strategy games ever created. Developed by Westwood Studios as a sequel to the groundbreaking Command & Conquer, Tiberian Sun and its expansion pack Firestorm continue the story of the GDI’s war against the sinister Brotherhood of Nod.
#29 Red Alert
Like Command & Conquer: Tiberian Sun, the original Red Alert was released for free by its publisher EA as part of a promotion for Red Alert 3. In this RTS, players can play as either the Americans or the Soviets in an alternate history, altered by the death of Adolf Hitler.
#28 Star Control II: The Ur-Quan Masters
Star Control II is arguably the best game in the trilogy of Star Control titles. Like other titles in the trilogy, it is a story-driven space exploration adventure game where the player (in control of the Captain’s Ship) interacts with strange alien races through hours of dialogue and occasional ship-to-ship combat.
#27 Quake Live
Quake Live is a new variant of Quake III Arena, designed to run on Windows, OSX and Linux platforms through a web browser plugin. The FPS features a number of updates over Q3A and allows players to go head to head in online duels. Players can participate in free-for-alls, capture the flag, and team deathmatch, to specialized modes like InstaFreeze. Quake Live enjoys an active community of both amateur and professional gamers and is one of the few online games intended to be played as a professional sport.
#26 Return to Castle Wolfenstein: Enemy Territory
Before there was Team Fortress 2, there was Enemy Territory. Developed as a free multiplayer add-on to Return to Castle Wolfenstein, players took on the roles of axis and allies in this heavily stylized Gothic take on World War II in an objective-driven multiplayer FPS.
