The biggest game on Steam is 2015 is...
A list of the best selling and highest earning games titles on Steam has been released, and there are plenty of familiar faces
The Steam service is an online store for games, where you can buy titles digitally and access them in your library anywhere. It's owned by Half Life folks Valve Software and makes a shedload of money from its many thousands of games every year. Steam Spy has done some digging to figure out the most popular titles on the service in 2015 and some of the titles are expected while others are a pleasant surprise.
3000 new games launched on the service in 2015, making it even more impossible for us to catch up with our libraries. That's up from 1900 in 2014 and the concurrent users jumped from 8 million to a staggering 12 million. And those folks bought an estimated 350 million games, some of which weren't even during sales - though more than 60 million of them were during the recent December free-for-all.
Now to the lists. Taken in terms of revenue, major releases with high list prices were naturally top of the pile, and it's also no surprise that Rockstar's (long delayed) PC release came out on top with over $160 million earned. And that's after successful releases on old gen and new gen consoles. Next up was Fallout 4 which has brought in impressive numbers despite only releasing in November 2015.
Things get a little more interesting further down the list, particularly in terms of sales. Survival games like Ark and H1Z1 continue to be immensely popular, and their lower revenue is a reflection of a smaller list price. Still you can't argue with the number of copies sold. Top titles like The Witcher 3, Life is Strange and Dying Light all make it into the top 10, and with DLC coming for two of them sales should continue into 2016.
