so recently i found myself thinking the same thing. with the massive range of stone available, it easy to stay in the stone age.
but if you cut those out of your primary index, cutting out the wood and stones and bring a stranger colour
and texture to your builds. you might find you start building differently. creating orc like hut buildings with nether, or mud hutted builds temples out of glass. sky builds.
you can still use the old wood and stone but as minor hints, rather then primary material.
build bubble cities with glass.
desert forests with prismarine,
mushroom forests with glowstone/sea lanterns
alien shards gouging the land.
create a story based on creature that visited these lands rather then grew up and evolved here.
i hope this helped and its not just my mad ramblings. x
