AAMFP - Side Fun + Location (How interesting and funny you found it ?)

[Fortigurn]

Most of the things you cant interact with in the game have physics enabled regardless, even some locked drawers had it enabled, So I doubt performance was the main factor. Its likely more so you dont end up using the wrong items in a puzzle, so its easier to complete.

That's exactly what I think, the aim was too streamline the available options and shove you down the corridor. Or the conveyor belt, to use a metaphor more appropriate to the game. Ironically a conveyor belt is exactly where you end up for the last part of the game.
