If you're in the mood for some gaming on the cheap you might want to check out the currently ongoing Humble "Jumbo" Bundle 8. It features a variety of games, most of which I know very little about, but what I can tell you is that Warhammer: End Times - Vermintide and Jotun alone are well worth the €6 asking price!
As for the other games, here's the full list of everything the Humble "Jumbo" Bundle 8 contains, as well as the amount of money you'll need to pay in order to get it:
Pay what you want
• Valhalla Hills
• Legends of Eisenwald
• The Journey Down 1 + 2 Bundle
Pay more than $6,41
• Warhammer: End Times - Vermintide
• Mystery game that will be revealed in 6 days
Pay more than $10
Additionally, you might want to take a look at the current Humble Monthly bundle. You can grab The Witness for $12 right now, and also get a whole bunch of bonus games early next month. Just bear in mind that the Humble Monthly is a subscription service, so if you're not willing to go for a second month make sure to unsubscribe after you get all of your games. And don't worry about being billed twice as recurring payments are processed around the 15th, so you have plenty of time to cancel if you so wish. And finally, have fun!
