Steam most-played games attention velocity (weekly)

Weekly player-attention ranking of the 100 most-played games on Steam. The official keyless Steam charts API (ISteamChartsService/GetMostPlayedGames) supplies this week's top 100 by peak concurrent players with each game's rank, last week's rank (-1 = unranked), and weekly peak player count; the official keyless Store appdetails API enriches every appid with name, type, free/paid, genres, release date, and developers. Each game carries its rank movement (rank_change, null for new entrants), a new_entrant flag, and a documented 0-100 attention_score = 100 * (45% min-max-normalized rank gain + 35% min-max-normalized log10(peak players) + 20% newcomer bonus), ranked as attention_rank (1 = hottest; ties: peak players desc, appid asc). breakout_flag marks new entrants debuting at rank <= 60 or games climbing >= 20 ranks. From the second weekly snapshot on, growth_pct reports week-over-week peak-player change versus the prior snapshot (null on the baseline, which omits the column). Columns: ISO week, as-of date (charts rollup_date), appid (primary key), canonical_appid (the store id appdetails resolved to - Valve redirects superseded entries, e.g. 730 to 2678630/Counter-Strike 2), name, store URL, game type, is_free, comma-joined genres, primary genre, release date/year, age in years, developers, publishers, rank, last week's rank, rank change, new-entrant flag, weekly peak concurrent players, week-over-week growth %, attention score, attention rank, breakout flag, enrichment_ok, row hash. Nullability: name and the enrichment columns are null when the Store API returned nothing for that appid (enrichment_ok = false); rank_change is null for new entrants; release_date/release_year/age_years are null when the release date is unknown or 'coming soon'. Caveats: peak_in_game is the week's peak concurrent-player count, not average or unique players; last_week_rank comes from Valve's own rollup and is taken verbatim; attention_score is a within-snapshot relative measure, not comparable across weeks; genre labels are Valve's own taxonomy. Sample use: order by attention_rank for this week's hottest games, or filter breakout_flag for the week's surgers.
