capabilities like HBO or Netflix. In general, Telltale offered its games as a one-time "season pass" purchase for the game's season when the first episode of the season was released, with the user then entitled to all planned episodes for that season. For digital purchases, this entitlement was handled through the digital storefront. In retail, Telltale published complete seasons after the season's digital release was over, but also adopted a model where they could publish, at the same time as the digital release, a retail disc that contains the first episode. The disc included a "season pass" entitlement to the remaining episodes to be digitally downloaded, tied to the disc itself rather than the user. This allowed for trading or resale of the retail product that can be played by others, which according to Stauffer, makes for a "nice in-between" market model that satisfies players, retailers, and themselves. For some of their games, Telltale developed additional downloadable content, such as 400 Days for The Walking Dead, or three additional episodes for Minecraft: Story Mode Season 1, which must be purchased separately from the season pass. With Batman: The Telltale Series and most of their subsequently released episodic adventure games, Telltale added a "Crowd Play" feature that can be used by those that stream their playthroughs on services like Twitch. Through Crowd Play, viewers can vote for an option for the streamer to select. While mainly a developer, Telltale also verified its self-publishing ethos; the only classic developer-publisher relationship was with Ubisoft for the CSI video game franchise. They have struck financial arrangements with GameTap for the first two seasons of the rebooted Sam & Max games, but their publishing arrangements have been chiefly made after the games were already completed and had already been sold via digital distribution. Telltale aimed to also present itself on as many digital platforms and avenues as possible. To date, it has released games through GameTap; on Microsoft Windows and OS X, through Steam and similar services, plus its own online store, on Wii via WiiWare and disc, on Xbox 360, via Xbox Live Arcade and disc, on PlayStation 3 through PlayStation Network and disc, on iPhone and iPad through iTunes, on PlayStation Vita, and on Kindle Fire HDX. Though Telltale normally port their own games to other systems, CSI: 3 Dimensions of Murder was ported to the PlayStation 2 by Ubisoft Sofia, and Bone:
