Odd thing ive seen

Has anyone else noticed a lot of like areas and area designs are reused in the fire emblem games?
Currently playing through awakening and dude im having DEJU VU with some of these map lay outs, seriously they are REALLY close to or almost the same to some of the ones in three houses.
Fire emblem engage also ngl just plays like a remake of awakening but kinda worse. Its just weird to me ngl, could just be something im imagnining but was curious if yall noticed anything similiar
