This is my first Telltale experience so I won't be making comparisons. Taking it from the top, TWAU presents the fables world very attractively. It goes straight to business in presenting concepts and their consequences. It really makes me want to give the comics a shot.
Characters are also a good hit for the most part, they're not stereotypically based on their fairy tale story and they each have their own depth. Only one character felt cringy and over the top (BM) but thankfully she isn't very prominent in the plot.

I liked the story a lot, while it does lose some steam going through, I understand because that stellar introduction is hard to keep up with. I rarely felt frustrated that the choice didn't match my intention or that consequences felt nonsensical.

The Teltale penciled style really fits the setting, it felt like a perfect match. There were technical issues but they all were either animation or facial-expressions related. I'm not a fan of QTEs, but it wasn't specifically bad or anything.
