Games like Star Trek Online

A typical game among these

≈ 10k–16k copies

≈ $36k–$67k after Steam's cut

from ~362 reviews

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

2 of the 8 similar games are hits.

Best case: STAR WARS™: The Old Republic™ at ≈ 1.9M–3.0M copies. It is a breakout hit, far above a typical game.

What their first month looked like

About half the games that made it here had over 212 reviews in their first month; the range was 28 to 7k.

The genre you'd be entering

These games: The similar games share MMORPG (6 of 8) and Open World (6 of 8).
The winners: Winners here lead with Open World. The breakout hits carry Multiplayer + RPG + Free to Play; a typical game here doesn't.
When they shipped: The similar games span 2010 to 2023, and none of them 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).
