I’m solidly middle aged and the last shooter I played regularly was a Battlefield game. Despite my age and there being a lot of players in any given match I got good enough at the game to move the needle on matches consistently and virtually always stayed on top of my team’s scoreboard.

Reaction time and aim is important but overrated. Understanding the game’s mechanics at an in depth level is far more important. This was true even back when I was a kid playing Halo PC and CoD4.
