I've posted my thoughts already. There is more to it than just looking at the numbers of people logged in to steam to determine "high end gaming is or is not in decline".I have not found it. Yes, of course the 90 million includesmultiple account holders, but I doubt there are that many of them. And there are 19 million people using Steam RIGHT NOW.
Anyway the issue was high-end gamers being in decline. Do you have any evidence to justify @beany_bot's assertion?
look at the number of concurrent users actually in game the last few years, has it increased?. Look at the games those people are playing, Do they require "high end gaming pcs"?.
I'm logged into Steam (have been everyday for a long time), my last game played on it was shadow of tomb raider in early June. Does that mean I have a high end gaming PC and I am looking to splash money on an upgrade?
