December and April looked to be the best months to buy Steam Games as estimated by Steamspy.

The gathered data covers the period of April 2015 to December 2015, and reveals that Steam had also bought over 3000 new games last year, compared to 2014’s 1900 and had 12 million concurrent users worldwide.

While the preliminary results featured Counter Strike – Global Offensive to be the platforms best seller by selling 5,634,096 copies, the most recent datamine reveals that Grand Theft Auto V would have to take the best selling spot from CS:GO when it comes to overall revenue.
