A Linux gaming distro, as the name suggests, is tailored for avid gamers. As such it usually comes bundled with games to play, as well as drivers for graphics cards, games controllers and so forth. 

There aren't many Linux distros specifically made for gaming. This isn't because Linux users dislike games, but rather it’s due to the fact that most modern Linux distros support virtually every type of recent graphics card anyway. As such, any regular Linux distro can easily be turned into a ‘game station’.
