Steam is building support for season passes into its platform and setting up rules to help protect buyers from buying ones with unclear promises. Steam published new guidelines urging developers to “think about whether there’s a customer benefit” for purchasing season passes, as reported by SteamDB creator Pavel Djundik.

Steam's new policies require season passes to specify content and release dates, with refunds for cancelled DLC.

Season passes are one of the most common ways to generate revenue for games such as Fortnite or Call of Duty that want players to keep returning day after day, month after month. This week, PC game platform Steam has rolled out support for this monetization approach.
