So, I have free prime for a month, I downloaded the app, but the games in the first category are not even in the store, and the SNK ones are not free. Does it have to be the paid prime and not the trial, maybe? Or because I'm in Italy, or my Prime app is in German for some reason and I can't change it?

If people are boycotting gog due to the devotion issue then they should be avoiding amazon for being ten times worse.

strange.

If you have prime, and downloaded the app as in the first post, then signed in with your Amazon account, then the games should just appear there. The app should look like the screenshot attached.

If it does not work, my first guess would be beacuse it is a trail, but you need to assk Amazon support (if that is even possible) about it.

Nice, good you figured it out. I should perhaps specify it is PC games in the OP, didn't even think of it.

eheh when I read "app" I can't think of windows software, but this is the new lingo so it's not your fault!
