It took me 120 hours to finish the game, but I did every quest, talked every NPCs, explored every location in the game.
You really stretched it out. I also did every location and quest, and I think I finished in around 50-60 hours.
I liked the first several hours of Outer Worlds a ton. Then it got repetitive and never recovered. I still think it was easily worth the money. The first area was enough and the dinner between Pavrati and the girl that looks like she came from Firefly was cute.
Parvati is the girl that looks like she came from Firefly.
I also liked the early game a lot. The setting felt fresh, and it was a decent challenge for maybe the first 10 hours. It takes a while before you start to realize how repetitive the game is and how poorly the itemization was implemented.
