Counter example: if you pick an Elder Scrolls game you can easily get 100 hours for a single playthrough. Then start again with a different class / race / playstyle for dozens of combinations. Not satisfied? They have one of the largest modding communities, for hundreds of hours of more gameplay.
You don’t need online / multiplayer to have an immense amount of replayability.
Also, the argument was about what is considered a good hours/price ratio. If you are telling me that your standards are dozens of hours / $, then yo do have a bit of unrealistic expectations.
For now.
