A breakout hit, far above a typical game.

6 of your 8 games sit in the typical range; 2 are breakout hits far above it.

Copies and revenue are rough lifetime estimates from the review count; typical figures are medians per column, so they can come from different games.

The lane you'd be entering

Winners here lead with Software + Utilities, priced around $5.
The breakout hits carry Simulation + Shooter + Realistic; a typical game here doesn't.
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.
A typical game here lands in Gold ($250k–$1M before Steam's cut, est.); the best case reaches Diamond ($1M+). Tiers: Chris Zukowski's benchmark tiers.
