Most game developers add extra content or Sooner release dates for Patrons. Example: "Fucking My Daughter" version 6.9 Update on the 5th of a month $5 access on the 15th. $10 accessible the 10th. Or those that offer $20 might access it on the 5th (immediately after the tested Update is available for download). Or they might grant assorted other benefits. Even though dumbass patreon censors Incest or Rape it's still slightly useful to pay than wait for general release on the 20th.
