The genre you'd be entering

Your set: Your set clusters on Sandbox (6 of 8) and Simulation (5 of 8).
The winners: Winners here lead with Sandbox, priced around $20. The breakout hits carry Moddable + Singleplayer; a typical game here doesn't.
The era: None of the games you compared shipped in the last two years; the newest is from 2020. That says more about your picks than about the market, so add newer similar games to read the timing.
