Gregory's ServerI know what Doom and Duke Nuke'm are. Played them in the '90s.
I imagine they're #BoomerShooter games because they're shooters, & were around when Boomers were in their 30s, having LAN-game parties @ the office while telling their spouses they were "working late".
But I wonder what characteristics you'd use to classify something as a BoomerShooter.
