This sequel was a long time coming. Thankfully, it shipped for PC and OS X at the same time. The story picks up four years after the events of the original Starcraft, and follows an insurgent group attempting to make its way across the Terran Dominion. Non-linear gameplay with regard to the campaigns keeps the game interesting, and is a minor departure from the original. However, the order in which the campaigns are done will not interrupt the narrative.
Units remain largely the same, with some additional specialized units available only for campaign play and not in regular multi-player, such as the Terran Wraith, Vulture, and Diamondback. There is also a map editor, similar to the original StarEdit, which allows for customization of terrain and campaigns.
XCOM: Enemy Unknown
Firaxis's XCOM: Enemy Unknown is a true successor to the turn-based strategy game series by Microprose. XCOM: Enemy Unknown sees the invasion of our cities by an extraterrestrial force that seeks, it seems, to purge mankind from the face of the planet.
Players are tasked with controlling a squad of earth's finest soldiers to take on the alien menace head-on in turn-based combat in locations ranging from dense urban environments to labyrinthine alien structures.
Revived by the makers of Civilization, the new XCOM streamlines everything that made the original title a little annoying to play through and improves upon all of its best qualities for a modern, turn-based strategy game that's like no other.
In addition to being released on the console, the game is quite thankfully playable on both the PC and Mac.
Minecraft
Minecraft began as a PC-only game, but it's since been ported over to the Mac and Linux, where it has enjoyed regular updates consistent with the PC version of the game.
The game's popularity can be attributed to the fact that it plays like a sort of multiplayer game of Lego, in which players can craft castles and kingdoms to their hearts content, or explore the procedurally generated wilderness for adventures that are unlike anything they've ever encountered.
Played both offline and online, the game is fully compatible with its PC and Linux counterparts so friends and family can play the game with each other on servers regardless of whether they're running the game on Windows or the Mac's OS X.
Other awesome games on Mac OS X
Borderlands 2: The framerate may not be the best for the Mac version of Borderlands 2, which is why we haven't thought to include it on this list. When Aspyr (they're handling the port) sharpens up the game' well consider it.
