If you have younger children and want to get some family-friendly games for them, take a look at the Humble Humongous Back To School Bundle that's filled full. Quite a good bundle this one, and I can approve of multiple titles in this that my own mini-me played through years ago. Almost all of them have Linux builds available too.

The bundle includes 37 items across different tiers:

• Pajama Sam's Sock Works
• Pajama Sam 2
• Pajama Sam 3
• Pajama Sam 4
• Freddi Fish 3
• Freddi Fish 4
• Freddi Fish 5
• Freddi Fish Maze Madness
• Spy Fox 3
• Spy Fox 3
• Putt-Putt Joins the Circus
• Putt-Putt Enters the Race
• Putt-Putt Goes to the Moon
• And lots more!
