Keep in mind that there needs to be at least a base-line familiarity with the objects in the world for a player to have any ability to grasp what is going on. Having absolutely everything randomized and procedurally stitched together so that players need to farm schlorps and fight sclolps while schleping schups with shoplups and slelpos will wind up making a player unable to tell up from down.
It takes some time to learn that plump helmets are food and make dwarven wine, for example, and when there were fantasy plants only in the game, there were only a few. Adding tons of crops came only with adding real-world crops so that players can just use their real-world knowledge of those things. If you randomize all the plants and still have tons of plants (including magic plant variants for different magic spheres), that's creating a ton of new things that a player has to learn (including which plants are edible and which are useless or poisonous or just used for making cloth) that also becomes useless knowledge in the very next game they play.
Add to this all the randomized animals and civilizations, as well, and you're setting up players to be barraged by tons of same-y sounding but very different new vocabulary they have to study before they can even start to enjoy the game.
This is more aimed at the direction this thread is taking than what the OP itself suggests, mind. Having a world where horses are still horses but they speak in this world isn't that hard to grasp when everything else is the same. But there's more reason than just lazy writing why a lot of sci-fi has "space rabbits" or
"smeerps" rather than stopping the whole show to explain why actually the life from Omicron Persei 8 is silicon-based and evolved from starfish-like ancestors, so all creatures are pentapeds for every damn side location a story passes through. Just saying it's basically an alien equivalent to a rabbit is enough for the amount of narrative use it provides, because it kills the pacing to do this explation a thousand times to populate an entirely procedural ecosystem. (At least, unless you were doing a story explicitly on exploring what alien ecosystems would be like, but even that would need giving analogues to the Earth equivalents of things just so people have a frame of reference.)
