A Third of Roblox Plays a Single Genre

One genre, a third of the platform

We split every live Roblox player by the genre of the game they were in, every week for 14 weeks. The result is more lopsided than most developers assume. Simulation alone accounts for about 32% of all concurrent players — more than the next two genres combined.

Everything else — RPG, Obby, Shooter, Adventure, Party — splits the remaining third between them.

Remarkably stable taste

The striking part is not just the concentration, it is how little it moves. Week to week, the genre mix is almost perfectly flat. Trends come and go inside each genre, but the overall split of where Roblox spends its attention barely shifts. The platform's taste is a slow-moving thing.

A note on "genre"

These are Roblox's own genre labels, which are broad and sometimes loose — "Simulation" is a big tent that covers a lot of the tycoon and collect-and-grow formats that dominate the charts. The exact boundaries are fuzzy, but the relative scale is clear and consistent.

What it means if you are building

Genre is a strategic choice, not just a label. Build Simulation and you are in the biggest pond on the platform — the most demand, and the most competition for it. A smaller genre means less demand but far less crowding, which is often where an underserved, winnable audience hides. The same concentration that governs individual games runs through genres too.

How we measured this

RoWatcher records live concurrent players for every game it tracks and groups them by Roblox's genre label. For this piece we summed concurrent players per genre each week over a 14-week window and charted the share of the total. Figures are from Roblox's public web API.
