PUBG: BATTLEGROUNDS

from 2.7M reviews

A breakout hit, far above a typical game.

7 of your 8 games sit in the typical range; 1 is a breakout hit 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 Survival + Shooter, priced around $14.
The breakout hits carry Third-Person Shooter + Survival + Shooter; a typical game here doesn't.
None of the games you compared shipped in the last two years; the newest is from 2021. 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 Diamond ($1M+ before Steam's cut, est.). Tiers: Chris Zukowski's benchmark tiers.
