I think you missed his point. In the past decade, even when they had PC exclusives and the consoles didn't have anything, sales of PC games still got dwarfed by console game sales. But PC gaming is a growing force, and this here is showing how it's evolving
This isn't true. The last time the PC had an exclusive and the consoles (PS3/360) didn't have anything was Settlers 7 in March 2010, when it WON against the PS3/360 that had nothing. On the rare occasion when PC gets exclusives and Consoles get nothing, it wins. It has won quarters where multiplat titles have launched as well.
Anno 1800 (Q1 2019/2020) - PC Won, no console titles.
Anno 2205 (Q3 2015/2016) - PC Lost. Anno 2205 bombed was the worst game in the series, AC Syndicate launched same quarter.
Might & Magix X Legacy (Q4 2013/2014) - PC Won. South Park Stick of Truth launched same quarter.
PC only won if you divide PS3 and PS4. Otherwise, Playstation comes up to 33% vs 24% on PC. Considering the game flopped enough on PC that they cut support after just 2 months with game-breaking bugs in the game, a total win would have been seriously troubling.
Shootmania Storm (Q1 2013/2014) - PC Won (Tied with 360), Comparatively small unsuccessful title. Far Cry Blood Dragon launched this quarter also.
Like you said, it only tied. And that's against a dying console generation.
Might & Magic Heroes VI + Anno 2070 (Q3 2011/2012) - PC Lost, Reason: Console dominated Q3, Just Dance released on Wii selling a crapton, Assassins Creed Revelation pushed 360/PS3. Rayman Origins multiplat release.
2 Big releases and yet PC lost. Badly.
Settlers 7 (Q4 2009/2010) - PC Beat PS3/360, lost to Wii. Red Steel 2 launched on Wii this quarter, Wii just being the Wii. PS3/360 had no notable releases this quarter.
Wii won, not PC, period.
PC has won even when there's been other multiplat titles released in the same quarter. PC losing when it has received a major exclusive and consoles have had nothing has not happened and would be shocking if it did.
A PC Win is completely expected.
