There are many ways in which gaming has advanced in the 21st century. One of the biggest stories has been the development of open worlds and developers' evolving approaches to the idea. Steam loves a good open world and that's why Valve's storefront is holding a massive sale dedicated to the open world. This sale features games like Cyberpunk 2077, Sea of Thieves, Disco Elysium, ARK: Survival Evolved, No Man's Sky, and many more. If you want to get lost in a giant world, this would be the weekend to do it. If that's not what you're going to Steam for, then be on the lookout for continuing deals on Outriders and Marvel's Avengers, as well as free copies of Company of Heroes 2 and its Ardennes Assault expansion and Little Nightmares.
