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.

As of August 17, 2026
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.
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.
