# Roblox vs Injustice 2

The clearest difference is ads: Roblox at none against Injustice 2's shown. Roblox also leads on update cadence (weekly vs every 2 months) and ratings volume (20M vs 173K). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Roblox sells 16 in-app purchases, starting at $4.99 per month and Injustice 2 sells 18 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 4.6 for Injustice 2. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 173K, 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 Injustice 2's.

Roblox ships an update weekly, Injustice 2 every 2 months. Both last shipped on September 24, 2026.
