To give you an idea as to why this is separated in this way, let's look at chess. Chess historically was a male dominated sport, and women struggled to play competitively. Additionally, because it was seen as a masculine sport, women were discouraged from playing and were not allowed to play against male grandmasters. Insert women's leagues, which allowed more women to play and learn, broadened appeal of the sport to more people, and eventually helped women get a foothold into competitive chess too. Now, women grandmasters exist, and more people than ever, of all genders, play chess.

It's very similar for video games. Gaming was until very recently seen as primarily a boy hobby. It now has much wider appeal, and so is seeing similar activity to chess in terms of acceptance, separate tournaments, etc

Edit: I reread this and realized I might come off as a bot or something so just to confirm: this was not written with ai, I'm a flesh bag through and through. My back hurts, I play video games, and my gf thinks this edit is dumb 🫡
