Amazon Prime Gaming. It's not something I write about too much, though that's primarily because it's not something I think about as much as I likely ought to. Why should I? Because I already subscribe to prime, and the bonuses are just on top of what I'm already paying for anyway. The other reason is simply that some of the giveaways are pretty good.

Case in point, from yesterday (1st of June) to the 21st of June, you can claim a free copy of Battlefield 4. Sure, it's not the latest Battlefield, but it's still a decent one. One that's still fairly active online and does have a decent enough single-player campaign for you to play through. Oh, and it's free, so there's no real reason not to pick up your Origin key if you already have an Amazon Prime Subscription.
