How many times have you completed Half-Life 2?

[Unfocused]

I completed it once on medium and once on hard. I don't know why people say it's too easy for them even on hard. In my opinion it has difficulty levels similar to other games. Maybe I'll give it a go for the third time but, again, on medium. I find the game more enjoyable then, cause you can mess with the enemies more, not just quickly kill them before they kill you.
