Gaming is a bunch of different nerdy subcultures in a trench coat, many of them really chill, some of them really toxic. Most speedrunning, indie, retro, and modding communities in particular are cool. There's also a "gamer" culture that insists that it's the only one and it owns all the cool things in these subcultures without participating in them, which is mostly focused on recent and upcoming AAA games, and it is just the most toxic horseshit there is. But those people actually don't interact with smaller gaming cultures despite insisting they own the umbrella, so you're unlikely to run into them outside of AAA gaming spaces, large twitch streams, and reddit.
