Sonder (still) sounds like a really cool game! To recap: it's a sci-fi game where you don't play as a single character, you play through the same events as every character. The more you observe and learn each time you play, the better prepared you'll be for your next go through.
Like Life is Strange, it also features a rewind button, which lets you experiment with the decisions you make; decisions that once made will stick, and be there for the next character you play as to experience/suffer.
Sonder is going to be episodic, with the first episode out on PC later this year.
