If you'd like to include a Season Pass as part of a pre-purchase of an edition of a game, you'll still need to set up a Season Pass DLC as usual. However, as part of setting up a pre-purchase, you'll need to contact Steam to set the Season Pass DLC into pre-purchase mode. …

In this set up, customers only pay for the items they don’t already own, making it ideal for players with partial content. You can create a Complete the Set bundle as outlined in the [doclink=/store/application/bundles]Bundle Documentation[/doclink]. …

[subsection]Solution[/subsection] The order of operations can matter here, as setting a build live doesn’t go through the publish process but changing the launch options does. If it’s only a few seconds between the two, it’s unlikely to impact many people as Steam will force an update when the user goes to launch and that should grab the latest launch options. Assuming that there’s a build update associated with the change, we recommend setting the build live and then immediately publishing the app admin settings with the launch option change. …

Please note that audio will be filtered down to regular stereo when we transcode the videos. [subsection]Advanced Settings[/subsection] The Advanced Settings can be used if you have trailers in multiple languages or need to restrict them to certain countries.

For example, if your game is being distributed on Steam by a publisher, then it's useful for both the publisher and the development studio to be set up with access to the game, even if payments for sales of the game will only go to one of the entities. There are a few ways to grant others access to your applications. …

[b]This method has the following advantages:[/b] [list] [*]You can explicitly set permissions for each individual user account. [*]You can control exactly which individual user accounts have access to your Application. [*]You can control exactly which packages are autogranted to the individual user accounts in the group. …

If a player is visiting your store page and if your product has content descriptors that the user has indicated they do not want to see (including defaults), they will be presented with a warning. This is keyed off the settings you entered in filling out the mature content survey while setting up your store page. These warning pages will let the player know that the content they are about to view is different from the preferences they have previously specified (or the defaults that Steam has). [section]Regional Rating Board Settings[/section] Players may also encounter an age-gate if you enabled age-gates while entering in ratings from regional rating boards such as ESRB or PEGI. …

Each playtime generator grant will be tracked separately if any of the drop settings are specified ('drop_interval', 'use_drop_window', 'drop_window', 'drop_max_per_window' ). In other words, if the itemdef does [b]NOT[/b] any drop settings, then it shares drops with all other playtime generators without drop settings and they are all limited by the application's drop interval. …

Alternatively it can be used to prevent any future drops of a deprecated item if the value is set to zero. We will only acknowledge this setting if the [code-inline]use_drop_limit[/code-inline] is assigned to "true". …

It is up to the publisher/developer to decide if they want to participate in the program and they are responsible for setting the commercial price. [*][h4]Does the Café Program work for schools and universities?[/h4] Yes. We designed the Café Program to be as flexible as possible. …

[/h4] We will have no limit on the number of PCs that the pool of commercial game licenses can be used across so as long they are all on the same network where the authorized Café Server is located.
