>>11793565>What exactly is dudebro anyway?The stereotypical party college fraternity guys. The ones that wear the popped collar polo shirts, baseball caps (often backwards or angled), heavy drinking and often refer to others as "bro."
The type that made fun of nerds in the previous game generation for playing video games but then began playing games themselves when the likes of Halo and such came out because video games were now no longer entirely gay.
Generally you can expect dudebro games to involve masculine activities (shooting, fighting, sports), graphics aiming for realism, simple pick up and play gameplay and competitive multiplayer. FPSes involving military action often check those boxes, so that's how Halo and CoD became associated as dudebro games.
