Raptr is an application that helps PC gamers by optimizing in-game settings, recording and streaming gameplay, and providing a chat service. Each month, they use their community data to compile a list of most played PC games over the previous month. This release concerns the month of March, 2015.
The top five games rarely move, but the last two months are minor exceptions. In February, Diablo III kicked Smite out of fifth place, leaving League of Legends, World of Warcraft, DOTA 2, and Counter-Strike: Global Offensive untouched above it. In March, DOTA 2 by Valve Software had its third place ranking usurped by their arch nemesis: Counter-Strike: Global Offensive by Valve Software. That is the only change in the top five segment.
Looking at the bottom three-quarters, Dragon Age: Inquisition continued its descent right off the list, allowing PAYDAY 2 and Spider Solitaire to both re-enter the top twenty. (Apparently Spider Solitaire dropping by the list made Raptr “sad”. It has been absent since November 2014.) Battlefield 4 is down and War Thunder is up. Battlefield Hardline was only tracked for the first two weeks after its release, because we ran out of March, but it didn't even come close to the top twenty, placing 49th. It is attributed to Battlefield 4's decline, though.
StarCraft II being the only exception, four of Blizzard's five current titles are in the top ten most played games on the PC. With the Legacy of the Void beta going on, I wonder if they will achieve a five-for-five (or six-for-six if Overwatch is available by then) when the game fully releases, whenever that is.
