I'm a big Otaku (fan of asian culture) and I love telltale games because they're the closest thing to a western version of a gaming genre called "Visual Novel" in which you're presented key decisions during a "game" (if you can really even call it that), and the choices you make uncover different "routes" and "endings" for the story. These games have huge replay value, and Telltale is a little lacking in replay due to only having one ending. But still there are some decisions which do effect what happens story wise which may make replay for some users worth it.
I do not need "gameplay" to enjoy a game. I play ALL of my games (regardless of what genre they may be) ONLY for the story, so if they have nothing BUT story, that's fine for me.
In Japan, there's even another subset of this genre, called a Kinetic Novel, (AND there are a few available on steam), in which you get NO freedom of choice, and literally just sit there clicking and reading.
They aren't really my taste. I NEED that freedom of choice and high replay factor
I picked up Eden* on Steam without realizing it was a kinetic novel and not visual novel, and despite it being quite good, I have yet to finish it due to losing interest.
If you enjoy games like Telltale's catalog of "interactive movies", check out some visual novels which are also available on Steam such as Prince Evangile, Little Witch Romanesque, Nameless, and Dandelion Wishes Brought To You.
Also for similar games check JAST USA, Manga Gamer, and Jlist / Jbox.
I recommend Stein's Gate by JAST USA and a bunch of titles from Hirameki International who are no longer in business, but their stuff is available on Jlist/Jbox. Such as Ever 17 and Anamundi Dark Alchemist.
