do you mean realism? for me, most immersive games are ones that keep you so focused on objective that you end up forgetting you're in headset. i also remember having small moments of awe every time alyx surprises me with its positional audio
>early hl alyx levels, some train
>throwing shit around, looking for resin
>carelessly threw a big case somewhere behind me
>split second later, can hear breaking glass, exactly right place, exactly right distance, exactly where it broke after i threw a case into glass window
i dunno why, but it was really hard "wow" moment for me

also, obviously vrchat. get into it and you'll feel like you're elsewhere to the point where it's hard to come back to irl
