I was just alerted to this playthrough of Quake 2 for MS-DOS by TheSlipGateUser which showcases the game play under DOSBox.
Honestly I’m terrible at Quake, QuakeWorld and Quake 2, but it’s great to see someone who knows that they are doing, and more so that under emulation the game is holding up.
I know the MS-DOS port isn’t exactly the most popular in the world, although I suspect if it had been a thing in 1997 there would have been an audience with people that didn’t want to have Windows in the background as a distraction.
That said, any new people will of course want to check out the excellent (if I do say so myself!) series “Porting Quake II to MS-DOS“.
