# Roblox vs Alien World

The clearest difference is ratings volume: Roblox at 20M against Alien World's 2.1K. Roblox also leads on update cadence (weekly vs every 5 weeks) and review sentiment (60% vs 46%). Alien World's advantage is iOS requirement (12.0 vs 14.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Roblox sells 16 in-app purchases, starting at $4.99 per month and Alien World sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for Roblox against 4.5 for Alien World. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 2.1K, so its average is the more settled of the two. Written reviews are what separate them: 60% of Roblox's written reviews are positive against 46% of Alien World's.

Roblox ships an update weekly, Alien World every 5 weeks. The most recent releases landed on September 26, 2026 and September 24, 2026 respectively.
