I have been spending a lot of time thinking about how Reddit shaped gaming culture at the start of the decade. Five years after the platform published its 2021 recap, the data still feels surprisingly relevant in 2026. Back then, Reddit communities ranged from unsolved crimes to cute dogs, shower thoughts and dad jokes, but the gaming corner of the site absolutely dominated the conversation. If you ever doubted that gaming was Reddit's biggest cultural engine, the 2021 recap should have ended that debate.
The biggest communities of 2021
According to the data, the biggest community was Genshin Impact. That might not shock anyone who has opened the app in the last few years, but at the time it proved just how fast a polished free-to-play open-world game could capture a global audience. Second place went to League of Legends, the long-running competitive juggernaut that keeps generating drama, strategy discussion and patch-day arguments. Third was r/gaming, the all-things gaming subreddit that acts as Reddit's front page for the medium. Fourth was r/rpclipsgta, a subreddit dedicated to GTA Online's roleplaying scene, which turned streamers into community celebrities. Fifth belonged to Final Fantasy 14, which made perfect sense because the Endwalker expansion launched that year and produced login queues so long they reached the thousands. Honestly, I would bet that a large share of those posts were complaints about queues and the famously disappointing grapes.
| Rank | Community | Why It Mattered |
|---|---|---|
| 1 | Genshin Impact | Massive global open-world hit |
| 2 | League of Legends | Competitive mainstay |
| 3 | r/gaming | Broad gaming hub |
| 4 | r/rpclipsgta | GTA RP streaming culture |
| 5 | Final Fantasy 14 | Endwalker launch and queue chaos |
The most popular posts
The most popular post of the year came from r/gaming and was simply titled 'boy gamer'. I still think about how effective it was. The post reversed roles to highlight the discrimination women often face in online games, showing how disturbing some of the comments they hear can be. It opened with a guy asking, 'Anyone got a mic?' A woman then responded, 'Is that a boy? I just want you to know I think it's cool that you're a boy. I'm not a pervert or anything but I want you to know that I support boys in gaming and I want you to feel comfortable playing online. So you got a girlfriend?' That role reversal cut straight to the heart of a problem many players would rather ignore. Was the gaming community finally ready to confront its own double standards? The popularity of the post suggested that many people were listening.
After that came a news post about EA no longer having exclusive rights to Star Wars. That was a massive shift because it meant other developers and publishers could now make games in that universe, opening the door for projects that would not have been possible under a single-publisher lock. Third was a prediction post for Worlds 2021, which showed how much fans craved esports forecasting and debate. Fourth was US Representative Alexandria Ocasio-Cortez playing League of Legends, a crossover moment that brought politics and gaming culture into the same lobby. Fifth was a meme titled 'Times change.' It captured players migrating from World of Warcraft to Final Fantasy 14. Some moved because they were tired of Blizzard's long-standing MMO, but others left because of the ongoing criminal investigation into accusations and reports of sexual assault, harassment and discrimination at Activision Blizzard. That migration was not just a gameplay trend; it reflected a growing demand for accountability.
Explosive subreddit growth
The subreddit growth numbers were even wilder.
-
NoPixel, a specific GTA RP server, saw a 267 percent hike in views.
-
Pokemon Unite's subreddit grew by 8,600 percent, which is remarkable for a game that had only just launched.
-
Deltarune, the Undertale spin-off, saw a staggering 328,000 percent increase in growth.
Could any other hobby produce that kind of sudden community explosion? It underlined that Reddit was not slowing down, and in 2026 the platform's influence on how we discover and discuss games still cannot be ignored.
Looking back, the 2021 recap was more than a list of subreddits. It was a snapshot of identity, controversy and fandom. Genshin Impact's rise, Final Fantasy 14's rebirth, the WoW exodus, the Star Wars licensing shift, and that unforgettable 'boy gamer' post all pointed toward a gaming culture that was becoming louder, more diverse and more demanding. I may be reading this from 2026, but the lessons still apply: Reddit communities do not just reflect gaming trends; they help create them.
