The game, however, has been renamed Micropolis, which was its original working title. Electronic Arts donated the game's source code to the One Laptop Per Child Program, which opened SimCity for free redistribution. The first SimCity was released in 1989 for Macintosh and Amiga computers, and quickly grew in popularity as both a city-building simulator and as an educational tool. The game was made free on its 15th anniversary in 2009. The Elder Scrolls II: Daggerfall, released by Bethesda two years after The Elder Scrolls: Arena, contained several features that later became staples in the franchise.

The game, which is known for its starting difficulty, can be downloaded for free through the Elder Scrolls website. The DOS-based The Elder Scrolls: Arena was released in 1994 and was made free by Bethesda in 2004 in celebration of its 10th anniversary. While StarCraft focused on futuristic space battles, the Command & Conquer franchise featured more realistic warfare, albeit with themes such as time travel.


Other C&C games have also been made free, namely Command & Conquer: Red Alert and Command & Conquer: Tiberian Sun with its expansion Firestorm. The original Command & Conquer, another iconic real-time strategy game, was made free in 2010 for its 15th anniversary. The only restriction is that players are not allowed to pick apart the game's files and use its source code for personal purposes. The game can be downloaded through the official StarCraft website with no strings attached.

To rekindle the interest of old players and to invite new players to try out the game, Blizzard made the PC and Mac versions of StarCraft free.
