Steam games market worth $3.5 billion in 2015

Sergey Galyonkin's Steam Spy, which keeps an eye on all sorts of Steam stats, comes out with fascinating titbits, like how refunds might not have hurt Arkham Knight that much, or that the average discount in this year's winter sale is lower than it was last time. Or, as the latest analysis tells it, that the paid game market on Steam was worth $3.5 billion last year.

Steam Spy estimates ownership of games—the figures don't come direct from developers—and it can't distinguish games bought elsewhere and activated on Steam from those bought via the Steam store. There's clear margin for error, but what's a hundred million dollars between friends?

In 2015, 3,000 new games found their way onto steam, up from 1,900 the year before, and 350 million games were sold. More impressive still, these numbers don't include revenue from free-to-play games or DLC. When you include purchases for Dota and Team Fortress 2, Galyonkin estimates that Valve controls 15% of the global PC games market.

Interestingly, it seems the tide of games sweeping on Steam has stopped accelerating (or at least is enjoying a rest before swallowing all that we hold dear).
