The dataset generation failed because of a cast error
Error code: DatasetGenerationCastError

Message: An error occurred while generating the dataset

Steam Catalog Dataset — State of Steam 2026
Open aggregate data behind The State of Steam 2026, a study of the top 10,000 Steam games by owner estimate. Every field is a public storefront / third-party-estimate fact — no personal data.
Built by Crawlora by dogfooding its own APIs: the game universe is seeded from
SteamSpy's owner-ranked all pages and enriched with the public Steam storefront (appdetails). The full
dataset is queryable live at https://api.crawlora.net/api/v1/datasets/steam-games/search (and via the
datasets_steam_games_* MCP tools).
What's inside
| File | Description |
|---|---|
data/summary.json |
The full aggregate rollups behind the study — pricing by year, review-tier & price-tier distributions, top genres, ownership concentration (Pareto), platform-support trends by year, review sentiment by genre. |
data/sample.jsonl |
200 sample game records (top by owner estimate), one JSON object per line — the shape of the queryable dataset. |
data/pricing-by-year.csv |
Titles, free-to-play share, median/mean paid price by release year (2006–2026). |
data/platform-by-year.csv |
Native Linux and Mac support share by release year. |
data/review-tiers.csv |
Games per Steam review tier (Overwhelmingly Positive … Very Negative). |
data/genres.csv |
Games carrying each Steam genre tag (multi-tag; shares add past 100%). |
data/categories.csv |
Games carrying each Steam category (Family Sharing, Single-player, …). |
data/price-tiers.csv |
Games per list-price tier (free, under $5, … $30+). |
data/release-years.csv |
Games per release year. |
data/review-by-genre.csv |
Titles, median review score, free share per genre. |
data/ownership-concentration.csv |
Owner share held by the top 1/5/10/25% of games. |
The CSVs are flat cuts of the same rollups in data/summary.json — pick JSON for programmatic use,
CSVs for a quick load into a spreadsheet or pandas.read_csv.
Sample record fields
appid, name, developer, publisher, is_free, price_cents, initial_price_cents, discount_pct,
price_tier, owners_min/owners_max/owners_midpoint (SteamSpy estimate range), owners_bucket, ccu
(peak concurrent), positive/negative/total_reviews, review_score, review_tier (Steam's
volume-gated bands), average_forever_min/median_forever_min (playtime), genres, categories,
metacritic, recommendations, required_age, release_date/release_year, coming_soon,
platform_windows/platform_mac/platform_linux, language_count.
Headline findings
- Ownership is wildly concentrated. The top 1% of games hold ~33% of all estimated owners, the top 10% hold ~65%, the top 25% hold ~81% — of ≈9.2 billion estimated owner-copies.
- New-game prices are climbing and free-to-play is retreating. Median paid new-game price rose from $4.99 (2012–2016) to $9.99 (2024); free-to-play's share of new releases peaked ~32% (2019–2020) and fell to ~8% (2024). (2025–2026 have small samples and are caveated in the study.)
- Mac and Linux support is collapsing despite the Steam Deck. Among top games, native Linux support fell from ~44% (2013) to ~11% (2024) and Mac from ~51% to ~20% — Proton makes native builds unnecessary.
- Top games skew overwhelmingly positive. ~73% land in a positive review tier, only ~2% negative.
- Indie dominates. ~59% of top games carry the Indie tag.
Methodology & caveats
- Universe: the top 10,000 games by SteamSpy owner estimate (of ~10,900 tracked at capture). The head of Steam, not the full ~90k+ long tail.
- Owner counts are SteamSpy public estimates (ranges), not exact sales. We keep min/max/midpoint; concentration figures use midpoints.
review_tierfollows Steam's own volume-gated algorithm ("Very Positive" needs 50+ reviews, "Overwhelmingly" 500+), so it matches the store label rather than raw ratio.- Recent release years (2025–2026) have small samples; the robust price/platform trends run 2012→2024.
- Snapshot date: 2026-09-07 (version 2). Version 1 was the 2026-07-11 pull the State of Steam 2026 article cites.
Versions
| Version | Snapshot | Notes |
|---|---|---|
| 2 | 2026-09-07 | Aggregates re-pulled from the same top-10,000-by-owners universe (304,450 live records). Top 1% hold 32.8% of 8.88B estimated owner-copies (v1: 32.9% of 9.22B); free-to-play 2,023 of 10,000; 2024 median new-game price still $9.99. data/sample.jsonl is unchanged from v1. |
| 1 | 2026-07-11 | The aggregate the State of Steam 2026 article is written against. |
