Until May 24th, you can download and play Portal (1st person puzzle platformer game that won over 70 Game of the Year awards) for free. This is to celebrate the launch of the launch of Steam on Mac OSX and SteamPlay, the new system that allows people who buy the PC version of a game to also have the Mac OSX version of the game and vice versa (if Mac OSX version is available, and the publisher has agreed to sign up). Eventually, SteamPlay will also include Linux, since Steam is also in the process of coming to Linux.
Valve is going to make their entire catalog of Source engine based games available on both OSX and eventually Linux through SteamPlay, beginning with Portal today and soon Team Fortress 2.
What does this have to do with Civilization?
Guess what? 2K/Firaxis has made Civilization IV Complete a SteamPlay game. That means if you own the Steam version, you now own both the PC and Mac OSX version. This strongly indicates that Civilization V will also be a SteamPlay game, if not at launch, then through an update sometime afterwards. Since Civilization V will require Steam, it means everyone who buys Civilization V, whether in a box or directly from Steam, will likely get both the PC and Mac OSX version for buying the game once.
