The Scorecard

We grade our own calls, in public, every week.

Every call publishes with a pre-registered metric before the week starts. The following issue grades it against that metric, and a miss runs with the same prominence as a hit. The record to date comes from our three internal June editions, written and scored under the same rules before launch.

This week's read

The Worlds Report - Issue #6

August 11, 2026

  • Roblox demand fell 7.7% week over week on a like-for-like basis, and Horror was the only genre that grew (+9.6%). The fall landed inside Q3, the quarter that is historically Roblox's seasonal high point, so the calendar does not explain it.
  • Roblox said what changed, inside the window. On August 5 the company said discovery now optimizes for measured long-term retention and accepts a lower frequency of impressions for games that emphasize short-term monetization, concentrated in the US under-13 audience, and a creator-facing post followed on August 6. Treat this week's genre shift as event-driven and possibly temporary: the company describes it as a test, it is a ranking gradient rather than a switch, and full rollout is late August or early September.
  • Shipping an update stopped predicting direction on Roblox. Seven of the eight biggest decliners shipped a content update inside the window and fell anyway (Grow a Garden 2 -58.0M new visits, Animal Hospital -52.0M, Candy & Chocolate Keyboard Escape -51.9M). The biggest accelerator shipped nothing: Murder Mystery 2 (+44.1M) was last updated July 23 and was first published in 2014.

Roblox Tower Defense / Strategy RBX -43.4% › 3.2% share
Roblox Obby / Parkour RBX -20.3% 2% share
Roblox Survival / Co-op RBX -14.9% 11.9% share
Roblox RPG / Adventure RBX -10.1% 6.3% share
Roblox Simulator / Tycoon RBX -9.8% 23.9% share
Roblox Sports / Racing RBX -9.8% 2.7% share
Three things to know about this chart. It is Roblox only this week, because Fortnite has no usable cross-week genre comparison: island codes rotate through discovery and the turnover between the two weeks was effectively complete, so any Fortnite week-over-week would be comparing two different sets of islands. Genres under 1% share are left off so a small base cannot own the axis, which removes Roblox Party (0.7%) and Other (0.9%). And the two Roblox measures sit on different bases by design: share covers this week's full set of games, while the week-over-week compares only games present in both weeks. They agree everywhere except Obby, whose 2.0% share is carried almost entirely by one large returning obby course with no prior-week figure behind it; compared like-for-like that genre is -20.3% and holds 0.2%.
Why things work where

Platform demand shapes

The meters show how much of each platform's demand the top worlds already hold, in the most recent week.

Roblox

top-10 share 55.7% top-1 11.7%

Winner-take-all. The top 10 hold 55.7% of new visits and the top title alone holds 11.7%. The median world took 46,832 new visits. Read these as levels rather than as a week-over-week move: the mix of games behind the comparison changed enough this week that the change in concentration is not a sound read.

Fortnite Creative

top-10 share 26% top-1 3.9%

Long tail. The median island peaked at 6 CCU on roughly 13.2 minute sessions. A fresh niche island is viable and disposable: the top island by peak CCU this week first showed up in our figures on August 6.
