Civilization series. lose count how many.
Taikou rissiden series, also spend many many hours into the games until lose count.
Uncharted Water series too, the hours add up maybe ish in years.
Xcom series, JA series, RTK series, Sims series, Master of Orion series and Master of Magic etc all also take up insane amount of moi times to pray when a new title ish out. If heng maybe half a year, if suay can pray for 2~3yrs before moving on.
So mainly ish those strategy type that will cause moi to invest insane amount of time to pray continuously one. RPG type typically 1 month can complete, some may need 2 or 3 month. But after completed once usually ish take months or even years later then will attempt to repray again. Like Suikoden one of the RPG that moi keep repraying throughout but in between always has few months to a year or two to take a break.
