Step by step

  1. 1

    Capture Steam review volume as the primary demand signal

    14,419 reviews and a 89% positive rating are used as the starting point because Steam review counts correlate strongly with paid ownership.

  2. 2

    Apply a calibrated Boxleiter multiplier

    For BioShock® 2, we use a midpoint multiplier of ×36 and show a wider range from ×20 to ×60 to reflect uncertainty.

  3. 3

    Use a realistic realized sale price instead of only list price

    Rather than relying only on the current price of $20, we estimate a realized average sale price of $10 to account for discounting over time.

  4. 4

    Translate gross revenue into developer revenue

    We then apply Steam's effective fee rate of 30.0%. That turns an estimated $4,983,206 in gross revenue into roughly $3,488,244 retained by the developer.

Revenue estimates for BioShock® 2 use the Boxleiter method with a broad range from x20 to x60. For the best estimate we use a calibrated midpoint of x36 and a calibrated average sale price of $10 instead of a flat 30x/0.75 model. Factors like age, price tier, discount history, genre, and review profile all affect the true reviews-to-sales ratio.

Frequently Asked Questions

How much has BioShock® 2 earned on Steam?

Based on our analysis using the Boxleiter method, we estimate BioShock® 2's total gross revenue on Steam at approximately $4,983,206.

This estimate comes with a confidence range:

  • Conservative estimate (x20): $2,768,448
  • Calibrated midpoint (x36): $4,983,206
  • Optimistic estimate (x60): $8,305,344

The actual revenue may vary due to regional pricing, seasonal discounts, and refund rates.

How many copies has BioShock® 2 sold on Steam?

With 14,419 Steam reviews and a 89% positive rating, we estimate BioShock® 2 has sold between 288,380 and 865,140 copies, with a best estimate of 519,084.

This is based on the Boxleiter method, which uses the observation that roughly 1 in every 20 to 60 buyers leaves a Steam review. For the midpoint we do not assume a universal 30x value; we use a calibrated multiplier of x36 that adjusts for the title's age, price tier, genre, and review profile.

How much does 2K Marin earn from BioShock® 2?

After Steam's tiered platform fee of effectively 30.0%, 2K Marin keeps an estimated $3,488,244 from BioShock® 2's gross revenue of $4,983,206.

Here's the breakdown:

  • Gross Revenue: $4,983,206
  • Steam's Fee (30.0%): -$1,494,962
  • Developer Revenue: $3,488,244

Note: This doesn't account for publisher shares, taxes, or development costs.

What percentage does Steam take from BioShock® 2?

Steam uses a tiered revenue sharing model that reduces the platform's cut as a game earns more:

  • First $10 million: 30% to Steam, 70% to developer
  • $10M to $50M: 25% to Steam, 75% to developer
  • Above $50M: 20% to Steam, 80% to developer

For BioShock® 2, with an estimated gross revenue of $4,983,206, this results in an effective rate of 30.0%. Steam keeps approximately $1,494,962 and 2K Marin receives $3,488,244.

How accurate are these revenue estimates for BioShock® 2?

These estimates use the Boxleiter method, a widely-used industry approach that estimates game sales from the number of Steam reviews.

Factors that affect accuracy:

  • Review-to-purchase ratio varies by genre
  • Discount history - games with frequent deep sales may have higher ratios
  • Regional pricing - different prices in different markets are not captured
  • Refunds - Steam's return policy means some counted sales were refunded
  • Bundled sales - keys sold through third-party bundles may not generate reviews

We provide a confidence range ($2,768,448 to $8,305,344) to reflect this uncertainty. For the best estimate we combine the Boxleiter range with a calibrated midpoint (x36) and a calibrated ASP of $10.

What would BioShock® 2 earn on Epic Games Store instead?

If BioShock® 2 generated the same gross revenue on the Epic Games Store, 2K Marin would keep approximately $4,505,222 - that's $1,016,977 more than on Steam.

At this revenue level, Epic's concrete platform fee would be $477,985. Epic charges 0% on the first $1 million in annual per-app revenue and then 12% on the remaining amount. On GOG (30% cut), the developer would earn approximately $3,488,244.

Note: This is a hypothetical comparison. Actual sales volumes differ significantly between platforms, and Steam's larger user base typically drives substantially higher sales.

How long do players spend in BioShock® 2?

According to SteamSpy data, players spend an average of 8.3 hours in BioShock® 2, with a median playtime of 2.2 hours. The large gap between average and median suggests a dedicated core community playing well beyond the typical player.
