For many gamers, one of the most appealing perks about an Amazon Prime subscription are the free games given away every month. In addition to receiving one, two, and same-day shipping, streaming video, and a limited version of Amazon Music, subscribers get access to Prime Gaming. This not only nets a monthly Twitch subscription to gift to a favorite streamer, but also free in-game items for various titles and, of course, a range of free games that changes every month.
