Verdict

The call

The clearest difference is rating: TerraGenesis at 4.2 against Space Simulator's 2.7. TerraGenesis also leads on review sentiment (50% vs 15%) and ratings volume (2K vs 93). Space Simulator's advantage is update cadence (every 9 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
