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 #7

  • Roblox demand rose 2.0% week over week on a like-for-like basis, and eight of eleven genres grew. Last week it fell 7.7% and one genre grew. Simulator rose 6.6% and ended a seven-week slide in its share of demand. One week of contraction was not the start of a regime, and last week's issue treated it as one.
  • We got the biggest finding in last week's issue wrong, and the correction is dated. We reported that Murder Mystery 2 grew 44.1M new visits having shipped nothing since July 23. Its content-update date now reads August 14, and July 23 turns out to be the launch of a summer event that runs to August 23. The game was mid-event the whole time. It is the biggest accelerator again this week at +56.7M.
  • Fortnite's GTA-6 theme was not finished. We called it dead last week at zero islands in the top-15. This week GTA-VI fan islands went from 2.8% to 14.3% of Fortnite CCU, put four in the top-15, and account for 85.8% of the RPG/Adventure bucket. Rockstar announced on August 6 that its next showcase airs August 27, so this is event-driven and it has an expiry date on it.

Roblox Obby / Parkour RBX +12.7% 2.2% share
Roblox Tower Defense / Strategy RBX +11.2% 3.4% share
Roblox Horror / Escape RBX +10.2% 16.1% share
Roblox Simulator / Tycoon RBX +6.6% 25.5% share
Roblox Sports / Racing RBX +4.4% 2.6% share
Roblox PvP / Fighting RBX +0.3% 14.7% share
Three things to know about this chart. It is Roblox only, because Fortnite has no usable cross-week genre comparison: island codes rotate through discovery and the two weeks share no islands at all, so any Fortnite week-over-week would be comparing two entirely different sets of islands. Genres under 1% share are left off so a small base cannot own the axis, which removes Roblox Other (0.5%) and Party (0.4%). 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. One entry needs a caveat of its own: Obby's +12.7% is one large returning course, which took 9.0M of that genre's 9.9M like-for-like growth.
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 54.3% top-1 12.4%

Winner-take-all. The top 10 hold 54.3% of new visits and the top title alone holds 12.4%. Read these as levels rather than as a week-over-week move: the mix of games behind the comparison changed again this week, so the change in concentration is not a sound read.

Fortnite Creative

top-10 share 25.8% top-1 3.2%

Long tail. The median island peaked at 6 CCU on roughly 13.1 minute sessions. A fresh niche island is viable and disposable: eighteen islands appeared against this week's GTA theme and none of them exceeded 3% of CCU on its own.
