Because that’s not the question.

I strongly doubt it can be a defining game as the other 2 were and are. Plus, for me, there is attrition in the need to use a non-polished control system.

I don’t how old you are, but the first one was the first very big implementation of scripted scenes. To see something happening in an FPS as in a movie was mind-blowing.

The second one is just absurdly well designed. And the visuals are imbued of this Eastern European architecture and vibe that right now, walking the streets of Warsaw, I am gladly breathing in.

Half life or Half life 2.
