My ex and I are both gamers -- I was a gamer grrl back in the 1970s, when women were considered freaks of nature if they were interested in "wargames." So when we had a kid, he was doomed, right?
My son was beating Civ on the MacPlus before he could read the text. My friends wanted to nickname him "Ender" but I told them they had to wait until he was old enough to read the book and decide if he liked the handle.
I have always played with him, and tolerated thousands of hours of theory crafting for games I never cared about, to the point where we called his enless prattle on car trips "listening to the Tyranids."
When my kid was in college back some years ago when LOL was on the rise and e-sports was very new (particularly in the US), he came to me to ask if he should stop out from school and try out for an e-sports team in CA. I thought about how I'd feel in his position. My own "twitch" is long gone, lol, and you're only young once. Should he take the path more travelled or take a risk on a dream?
He'd been making small change coaching people in LOL -- he was well ranked.
I took a deep breath and told him to go for it with my blessing. My friends thought I was NUTS, but I told them that e-sports was going to be bigger than American football and maybe not so big as Association Football in just a few years -- and I was right.
My kid didn't make the team -- but he came back to his "real life" with a confidence of having pursued and dream and resolved it.
A few years later, I became fully disabled -- he's about 30 now -- and he is taking care of me. I have told people if you told me when I was working I could game and blog all day, I'd say OH YEAH! But I didn't think the devil's bargain would come with a walker and many days confined to bed playing on my phone. But my kid and I are tight, and a lot of it is due to gaming together for a quarter century. Not many kids would take their mom in at his age and get along, but we do better than most housemates.
And I still smile and nod when he goes off on his "Tyranid" rants on his latest game -- because I don't "twitch" anymore, I can't really game with him in his best genres. But we share our metagames, and that's enough.
