I'm not sure I've lost the reflexes. Maybe I have, but I can still be competitive in these games with enough time for practice.
But that's the problem. Time.
I've got a full time (plus mandatory overtime) professional job, a stepson, a house and a yard to take care of, etc. etc.
I'm lucky if I get a couple of hours a week to spend in a game many weeks.
Compare this to my Counter-Strike days in college when I averaged more than a full time job playing CS. Some weeks it was over 60 hours.
I just can't compete with kids who have an infinite amount of time to practice.
Like everything else, use it or lose it.
Exactly. I have friends that have barely touched FPS or competitive games in many years while I played 6000+ hours of TF2 plus various other games over that same period. But Fortnite has brought them out of the woodwork and, while it's been a blast playing together, to say that we often have different expectations of our level of play would be an understatement. Not only are your own mechanical skills going to be rusty or simply not developed, but you'll be playing against people that have played a significant amount of hours and developed their gamesense, situational awareness, etc.
It's just funny because you see it a ton even here on an enthusiast board, people saying "I used to play UT but I can't keep up with these kids!" Yeah, we all played UT like 15 years ago. If you haven't touched a competitive game since then you're gonna need some serious practice time to get back to where you were.
