That's right, Battlefield 1 is FREE right now for PC on Origin. There's a catch though, you have to be a Prime subscriber. So if you have Amazon Prime, I suggest you go and grab the game right now while you still can.
And not only that, come back again on August 2, 2021, because Battlefield V will be given away then also on Origin if you have Amazon Prime subscription.
Those are the two games you can get on Origin if you have Amazon Prime subscription.
Here is the link.
Now, onto the Final Fantasy XIV deal.
Over on Square Enix, they are having an FFXIV sale.
FFXIV: The Complete Edition is available right now for $23.99 which used to be $59.99, so it is quite a good deal to get right now.
If you just want to get the Shadowbringers: Standard Edition though, it is also available with a discount, you can get it for $15.99 which used to cost $39.99.
Here is the link for the FFXIV deals.
I hope this helps.
