Headcanon says Sollux is one of those gamers who only plays newer console and PC games, and he makes fun of people who play games with ratings lower than T (yeah, one of THOSE elitist assholes). Karkat really likes the old classics, and is a pro at them, and plays newer games too but he's not as extreme as Sollux, who needs to get every achievement in every game he plays, and spends so much time playing just to be the best so he can shit on everyone he plays against online. So when they play games together, they ALWAYS play games Sollux likes, because he says Karkat's games are for babies and are 2tupiid and dumb and way two ea2y for 2omeone liike me. Karkat never fails to lose at these games, and Sollux gloats so nastily that Karkat leaves and doesn't talk to him for days. Karkat finally gets fed up with it, and brings over Super Mario Bros and Ninja Gaiden and Mega Man and Ghosts and Goblins and watches as Sollux can't beat any of them and throws a fit and locks himself in his room. A few days later he apologizes to Karkat and says maybe tho2e aren't really baby game2 and they were actually pretty fun and could you 2how me how two play them 2ometiime?
