Meanwhile Steam over there, cutting down support for Windows 7 and 8. Which narrows people's visitation when it comes to old games. Like, Steam is not notorious for the upkeep of old games, let's be honest. They never were. The only games they cared about supporting is understandably, their own when it comes to modernizing. But a lot of the time, you see old DOS games released on there, old Win 9x/XP/7/8 .etc games released and they have aged poorly. The publisher nor developer lifts a finger, leaving it to community to do the leg work.
That is why the idea of Valve cutting Windows support offends me, because if you aren't going to put in the work to make old games work as fluently with modern Windows OSes, why bother cutting support? Because some games, actually ran better on older hardware and yes I get it, coming across old hardware tends to be a challenge but virtualization and emulation doesn't simply cut it. So that leaves again the only option is for Valve to swing that multi-billion dollar hand around, to get a program, that will make all old games run as well on modern systems.
This is where GOG has always been strong in.
