The Humble Monthly subscription plan delivers you a selection of new games (to keep!) every month, gives you 10% off everything in the Humble Store, and donates 5% of each month’s proceeds to charity.
This month, they’re kicking things off with Quake Champions, The Elder Scrolls: Legends, and The Elder Scrolls Online, in addition to whatever indie games they roll out throughout the month. Again these are yours to keep with anymembership, even if you cancel it. Month-to-month subscriptions cost $12, and can be cancelled any time, but you can save more if you pre-pay for longer periods.
