GamesIndustry.biz has some analysis of new game releases on
Steam for 2019
based on data from sleuthy website
SteamSpy. While more games came out on Valve's store/service last
year than in 2018, they report a "major slowdown" of new
releases. They call this a change of pace, as they note the rate of new releases
increased "rapidly" each year starting in 2014. They also report the number of
new games owned is down significantly year on year, but caution that this is not
based on sales, just copies owned. Here are some figures:
Last year 8,415
games arrived on Steam, compared to 8,167 in 2018. With the number of games
released on Steam rapidly increasing since 2014, this represents a notable
change in pace.
The number of games released on the platform saw its first major leap in 2014,
increasing to 1,609 from 557 the year prior. Since then, the number of games
releasing on Steam has increased to nearly 2,000 a year.
The effect of this slowdown is seen throughout the data for 2019, most notably
with the number of copies owned falling from 242 million in 2018 to 127 million
in 2019.
SteamSpy is unable to provide precise sales data, but the number of copies owned
"refers to total copies of games released this year acquired by users for the
lifetime. Includes copies sold, downloaded for free and given out."
