Depends on the game:
- dropped Oblivion after 80hrs, was a blast up until the last 10
- sank 300+ in Fear & hunger, love/d it so much that I had to see literally everything it had to offer (lost my save before seeing the content mod, it was amazing but there's no way in hell I'm starting over, not when Termina is still there)
- beat XCOM 2 like 7 times, every playthrough takes months
- dropped Abiotic Factor after an hour
- did exactly 2 missions in Chernobylite - feels unfinished, #2 has amazing potential (will play it finished, EA sucks ass)
- last playthrough of FO4 was a thousand hours ... had more to do, but honestly couldn't indulge anymore
- dropped COD Vanguard & Black Ops 6 after 1 mission
If it's mid - 20-50hrs (E33 is amazing, but the emotional damage was too much & I still haven't continued it, idk how long it takes),
if the content loses flair quickly - 5-10-20hrs, if it's great you can deal with a hundred and more, and if it's a masterpiece ... modders will find a way to make it infinite.
All in all mid & upwards, otherwise why bother :)
