LOLIs it? You've compared clips from some random pro to a "noob" at HL1. As someone involved in that scene I can tell you that nothing has changed - FPS/twitch shooters are exactly as they've been since those days. I've played HL/CS since their inception and still do, at a top/sub-top level (~20-22k Premier; allegedly top 1%?); tried Valorant - same level rank (Immortal) after a month or two, CoD was similar back in the Original MW2 days.
Point is, (other than obviously to brag about being a nolife nerd loser who will easily 1v1 you all), these games have remained the same - graphics have improved and not much else, core mechanics are the same.
I would smoke you boy.
