To be clear, I did played the game back then. I did not perceived it as subtle or indirect or needing to figure out. Back then years ago, that in the moment game moment was "ah, OK, soldiers are supposed to be bad guys and I am supposed to kill them".

Back then, half life was one of the games that made me think about how linear games are evolving to be. At one place, you could decide to go left or right and it joined back together quickly. It was straightforwardly prescripted, which is something we discussed with friends a lot.

I did not needed hindsight of years and my current experience. If anything now I have less experience as I spend significantly less time playing games like this.
