Steam Next Fest is a week-long celebration featuring hundreds of FREE playable demos as well as developer livestreams and chats. Players try out upcoming games on Steam pre-release, developers gather feedback and build an audience ahead of their Steam launch, everyone wins!

They do - it’s called “early access”
Kind of like the Pizza Hut demo discs for PS1?
