Did the prediction match what actually happened?

We hid Summon and predicted how it would do from its 8 similar games. Every figure here, including Summon's, is estimated from Steam reviews.

Copies, estimated from reviews

typical (middle half) 12.3M–21.4M

best case 125.7M (PUBG: BATTLEGROUNDS)

Games like Summon

A typical game among these

≈ 12.3M–21.4M copies

≈ $95.8M–$383.1M after Steam's cut

from ~269k 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.

No genre covers most of these similar games. The closest is First-Person (4 of 8), so its genre is hard to place.

Of the 416 indie games that passed 1,000 reviews in 2022, 11.8% were novel genre mixes and 88.2% stuck to an established genre. Published indie market research.

Best case: PUBG: BATTLEGROUNDS at ≈ 95.8M–155.7M copies. It is a breakout hit, far above a typical game.

The genre you'd be entering

These games: The similar games share First-Person (4 of 8) and Co-op (3 of 8).
The winners: Winners here lead with Survival + Shooter. The breakout hits carry Battle Royale + PvP + Third-Person Shooter; a typical game here doesn't.
When they shipped: None of the similar games shipped in the last two years; the newest is from 2018. That says more about which games were found than about the market.

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 38 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).
