Is Prime Gaming useful if I do not play PC games?

Yes — Prime Gaming can still be useful even if you do not play PC games, but its value is usually smaller.

It may still be worth it if you use any of these benefits:

1. One free Twitch channel subscription each month
   If you watch a streamer regularly, you can use the monthly free channel sub to support them and get subscriber perks like emotes and sub-only chat.

2. In-game loot for games you actually play
   Prime Gaming sometimes offers bonuses such as cosmetics, currency, or boosts for supported games. If one of those games is on a platform you use, that can be a real benefit.

3. Cloud gaming or other current Prime Gaming/Amazon perks
   Depending on your region and the current offers, Prime-related gaming benefits may include cloud-gaming or other rotating perks. Availability can change, so it is worth checking the current Prime Gaming page.

When it may not be worth it:
If you do not use Twitch, do not play any supported games, and do not care about cloud-gaming-style perks, then Prime Gaming probably has little value for you.

The free games and game downloads included with Prime Gaming are usually most useful for people who do play games on PC or through a supported cloud service, so they may not matter much if you never play on those platforms.
