It must be: Myth The FALLEN Lords

I hope all 3 of them. :)

I'm not aware of any Oral Sex simulators, though I'm sure some may exist in Steam Green light.

One Must Fall.

Or perhaps Descent to Undermountain.

Maybe it's something completely different like Ski or Die.

Bioshock 1 & 2 and/or Song of the Deep.

It's Blade Runner! ( :

Half-way through the game, Ray McCoy has to completely re-evaluate his life, and the people that were once his friends, are now trying to take him down.

Yes that does look promising for it.

The Journey Down?

Apparently there's a Windows version of Elevator Action II / Elevator Action Returns.

Of course it can be no other game than Bloodwych and its sequel. :-)
