Level Design Mistake: Great Hall
I couldn't help but notice an error in the level design of the Great Hall (throne room) of the Red Keep. Most people probably won't even notice this, but if you do it breaks the immersion and feeling of continuity with the show a bit.
The scene where you enter the Great Hall to confront Cersei and Tyrion takes place in Season 4, just before the Purple Wedding. However, the large columns in this hall have the yellow design with vine decorations from King Robert's reign. In Season 2, Joffrey ordered the Hall to be modified; the vine motifs on the columns were removed and replaced with large, metallic braziers constantly ablaze.
Was this completely overlooked by Telltale? Otherwise loved the first episode; this was the first Telltale game I've played so far. Devastated by the ending though, I don't like the fact that your choices don't matter much here.
