If you enjoy playing games on Linux, there are some nice games in the new Humble Indie Bundle 7 that was made available today: https://www.humblebundle.com/. It is pay what you want, though to get the bonus games (Dungeon Defenders & Legend of Grimrock) you have to pay more than the average.
I'm having a ball playing Legend of Grimrock right now; for those of you that are as old as me and have played Eye of the Beholder back in the day, this is a very similar game. Runs perfect on my Intel Core i5 processor with integrated Intel HD 3000 graphics (Sandy Bridge). Haven't tried the other games yet, putting my teeth to Legend of Grimrock first
