Especially now that graphics cards like the Nvidia GeForce RTX 3080 are getting huge price bumps due to shoddy availability, you're going to need to save every penny you can after you buy one – and the best free games will let you do just that. Plus, building one of the best PC games is extremely expensive. Games like Paladins and League of Legends became so huge precisely because anyone can buy them and play them at any time. The low price makes it easy for all of our friends to get the same game and get playing together.
The best free games are kind of what make PC gaming so great – while big titles like Deathloop might get all the fanfare, the free games are what us PC gamers really play the most with our friends.
