I wouldn't jump on Humble Choice right now. Wait until the end of the month, they've done Black Friday deals every year where you can get a discounted one year subscriptions. I was skipping months I didn't like, or already owned the games I wanted. That let me stretch out one year to three.
There's also the weekly free games from Epic, and between Christmas and New Years they normally put out really good games for 24 hours only. If you subscribe to Amazon Prime, you also have games included with that which are your's to keep even if you cancel prime. They activate on an Amazon account, Epic, or GOG depending on the game.

And then PC gaming has bundles. Humble hasn't been as good the last few years, but there's occasionally an amazing one. GreenManGaming has just started doing their own bundles and they have been really good.
