I dont know what you considere a gamer to be.
I had friends come over with their playstation (first one) and use link cables to play red alert 1 vs eachother, then the same with the first xbox playing halo with link cables vs eachother.
I played for the national team in Unreal Tournament back when clanbase was a thing, I did around 20 international lans in europe in both unreal tournament and counterstrike source.
I had around 10k hours in world of warcraft, 5k+ in counterstrike source back when Xfire was still a thing and steam didnt even count hours played.
Guess I'm a gamer, still to this day, some of my best friends are people I met on counterstrike servers and lan parties almost 10 years ago :D
We don't no life games anymore like we used to, these are people that I used to game 10 hours a day with. Now I see them at least once a month going clubbing or getting drinks.
Still play a match of CS once in a while.
