Something all the Infinity Engine games + the Fallouts have in common was a running world clock. Time passed, morning to night. You have clear day and night times with associated activities reserved for each period. Characters are fatigued and need their sleep period.
Recent games have done away with this. This has made things easier for both the player and developers alike and is more convenient for gameplay purposes. That said, I never got comfortable and in many ways, negatively affected immersion into the game world.
Let's do away with this convenience shall we?
