Verdict

The call

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.
