whenever I go back and play 1.6, I'm always amazed at how crisp and direct the controls feel. it's hard to describe the feeling precisely, but modern fps games (even csgo to an extent) just seem clunky in comparison. it's almost like the feeling you get when you forget to turn off vsync. not sure if this is just my nostalgia kicking in or if there's a technical reason for this.
I totally get what you mean. The gameplay itself is just.. different. Not the story or whatever but strictly the movement. What you wrote about vsync just hit me on another level. I remember playing CS Source (don't ask) and that was just awful, I still played it for hundreds of hours, but it just was not hitting it like before. I think there is a technical reason for it, because I turned on CS 1.6 in between these comments and the difference was noticeable immediately
