Episode 2 represented a major increase in scale over the first release. It added 4,035 new renders and 152 new animations, bringing the game to more than 5,400 renders and 190 animations before counting optional Extra scenes.
The update also added new music, sound effects, characters, racing content, a mini-game, a redesigned main menu, a favorites gallery and a glossary app. Several underlying systems were cleaned up, including the personality-variable rework and many Episode 1 fixes.
The script itself was enormous: the development estimate listed roughly 186,000 words for Episode 2-related material and more than 22,000 new lines of code. The expected playtime was over six hours.
