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.

A new section added to Steam's guidelines focuses entirely on season passes and includes new rules on release schedules for included DLC.

It's going to be a lot easier for players to get refunds after Steam lays down new rules for season passes and DLC.
