as a game developer: they really are. the finer details are different, but the primary mode of interaction is pretty much the same. you bob and weave around rapidly while shooting at enemies who shoot back at you and a lot of the locations you fight your way through are pretty similar structurally to classic doom levels. they even have somewhat similar music styles. it's not bad for them to have the same fundamentals! it's important to recognize our roots and know the difference between something truly and fundamentally different vs something that is just extremely refined and iterated.
