Amazon Prime users have free access to stream on Luna, basically all Ubisoft games, and starting to get EA games, and Madden NFL 26, and EA FC 26 are exclusively on Luna streaming for launch. You buy the games on the Ubisoft or EA PC stores respectively.
So if you have a laptop, or android/iOS tablet, you can stream those games via the Prime subscription you already pay for.
Try the Nvidia GFN free tier as well. And since Sony is taking their long time to expand, xCloud also has Series (current gen) games to stream. Things you may not be able to stream with PS+ Premium.
