The middle of these games

≈ 907k–2.2M copies

from ~31k reviews

All 8 of your similar games are hits.

Your picks lean toward this genre's biggest survivors; the typical figure reads from its ordinary successes.

Best case: Lost Ark at ≈ 5.0M–8.2M copies. A breakout hit, far above a typical game.

What it took to get here

About half the games that made it here had over 21k reviews in their first month; the spread ran 4k to 128k.

The genre you'd be entering

Your set: Your set clusters on MMORPG (6 of 8) and Action RPG (3 of 8).
The winners: Winners here lead with MMORPG + Open World, priced around $27. The breakout hits carry Action RPG + Hack and Slash; a typical game here doesn't.
The era: The games you compared span 2013 to 2024, and 1 of your 8 shipped in the last two years.

How these numbers were worked out

A hit here: 1,000+ reviews, roughly $150k+ before Steam's cut (a standard indie benchmark).

Copies come from each game's reviews times a sales-per-review rate that falls with release age, from about 31 for the most recent game here to about 79 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
