So I don't know whether you've heard of it but there is this site called Cheapshark that aggregates most of the digital game stores and even allows you to customize your searches according to pricing, ranking, etc. I basically refer to it for ALL my purchases now. And they give out free games regularly. Surprisingly, their fan base is rather small (well on Facebook at least). They should have gotten bigger by now. So check it out and you're welcome!

dude, the free game is not by cheapshark. its by other website/game seller for example that free game shown in pic is given by EA Origin's On the House. They been giving out free game almost on monthly basis i think. cheapshark just giving out real time prices of digital game.
