December tends to be one of those months chock full of holiday deals, and the Internet is more than happy to get in on the festivities. This is especially true when it comes to video games. Sure, these kinds of promotions are mostly just clever marketing ploys, but cheap games are cheap games, and free games are even better. GOG, an online purveyor of video games, is currently running a promotion where they're giving away copies of Duke Nukem 3D. Not only are they giving it away, but this marks the first time that the game's been available for Mac OSX.
Duke Nukem 3D
Built on Epic Games' Unreal Engine 3, Duke Nukem: Next-Gen, a fan-made remake of the 1996 venerable, campy PC first person shooter, Duke Nukem 3D, has been officially approved by current Duke Nukem 3D license holder Gearbox Software, in yet another act of Gearbox being totally awesome.
