If you have a bit of free time and the will to experiment with different genres, I would highly recommend you go and check out the October Humble Monthly bundle. The reason I say this is because they are currently offering Hollow Knight, Hitman (the entire first season) and 7 Days to Die for an extremely low $12 combined.
I'm not a huge fan of survival games so I must admit I don't rank 7 Days to Die that highly, but both Hitman and Hollow Knight are well worth grabbing for $12 on their own, which makes this package an absolute steal in my eyes. I especially recommend playing Hollow Knight as it's without a single doubt one of the best Metroidvania games released in quite a few years, both in terms of visuals and gameplay. So once again, if you have a bit of free time, do make sure to check the current bundle out as it really is a great deal.
Before you whip out your wallet, however, it is important to mention that the Humble Monthly is a subscription service. In other words, if you're not interested in continuing, make sure to unsubscribe as soon as you can. You'll still get to keep all of your games, and you'll also get all of the bonus ones once they arrive next month, so there's really no reason not to do so unless you're willing to give November's bundle a chance as well.
And just for good measure, allow me to leave you with one of Hollow Knight's trailers. Hopefully it'll tell you why I am more than willing to shower it with praise. Enjoy!
