Games like Mass Effect™ Legendary Edition

A typical game among these

≈ 7.4M–8.0M copies

≈ $143.0M–$168.3M after Steam's cut

from ~198k reviews

Only the top fifth of 2019's Steam releases earned $34k or more before Steam's cut, so plan for that or less.

All 8 of the similar games are hits.

These similar games lean toward the genre's biggest winners; the typical figure comes from its ordinary successes.

Best case: The Witcher 3: Wild Hunt — Remastered at ≈ 43.8M–71.2M copies, ≈ $602.5M–$1620.0M after Steam's cut. It is a breakout hit, far above a typical game.

These games

The winners
Winners here lead with Story Rich + Choices Matter, priced around $55. The breakout hits carry Choices Matter + Fantasy; a typical game here doesn't.
When they shipped

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 61 for the oldest, then widened into a range; revenue rides on that estimate times price. Source: GameDiscoverCo (2020) and VG Insights (2021).
