If you want 100%, It's 80+. A lot of the length comes from the fact that each game within the game has multiple little routes within it.

The "defuse the bomb" game is a perfect example. It's a series of bomb-defusal puzzles, and your team of 3 have 3 disabilities spread between the 3 people: blind, deaf, mute. Most games would railroad you into 1 disability to streamline the content, but Game of Fourtune lets you pick your own disability, which leads to different puzzles and content in 3 different variants of the same game. If you're blind you don't get to see the CG and have to rely on finding contradictions in the text to solve the puzzles, or if you're mute you can see the CG but have to solve the puzzle by listening to the dialogue from the others to catch miscommunications and then you get choices for gestures to make to try and get your point across. The game goes the extra mile all around, you only need to solve 3 but there's 4 puzzle sections, so they have alt variants of the failstates on each round too (fail 1st vs fail 2nd and die).

Repeat this level of depth across something like 40-50 games, and then add on the actual core plot of this game itself, and it adds up fast. I think my total playtime was about 90 hours and that's excluding time spent in my notepad doc taking notes.
