While I love Telltale Games and have been purchasing their games since Sam & Max, there's one thing that is really, really annoying me since The Walking Dead, and now with The Wolf Among Us. At the end of each episode there's a hugely spoilery preview of the next episode. There's no way to skip it, and it occurs immediately upon finishing an episode, but before important things like choices and (important to me) credits.
It's doubly annoying because being forced to turn off sound and look away or leave the room (I mostly do the latter) leaves me irritated or angry, and that's no way to end an episode. For all the enjoyment I've gotten out of these games, the last feeling they give me is always annoyance. That's obviously not a good thing.
I would be most happy if the episode previews were ditched altogether, but at least give us the option to skip them, or better yet, let us disable them completely from the options. They are not a necessary part of the experience. Indeed, I would argue that they lessen it.
Unskippable cutscenes is a gaming sin I can live with. Unskippable previews is not.
