Eight years ago, Valve introduced a generous refund policy for Steam users. You could get a refund on any game, no questions asked, within 14 days of purchase as long as you played for less than two hours. However, this policy didn't quite apply to Early Access and Advanced Access games.
In these programs, players could enjoy a game early before its official release, but playtime during that period didn't count towards the two-hour limit. This meant some could essentially play most of the game and then request a refund before release. To address this loophole, Valve has updated its policy. Now, any playtime in Early Access or Advanced Access will count towards the two-hour refund limit.
