Violence! Blood and gore and people having their faces pulled off by body horrors. People getting into fist fights and shooting fireballs out of their hands while firing their laser eyes. Meticulously crafted guns shooting people with bullets. Nuclear strikes. Jet combat. Lizard people shoving broadswords into the chest cavities of wolves, then summoning zombie slaves to rip the throats out of city guards. Space mechanics being beaten to death with their own legs. This is gaming.
