Let's come up with a rich and complex alien world setting suitable for stories, pseudo-documentaries, or roleplaying games such as DnD. This can be an involved process, so I'd like you to just cover the basics first. We can refine the details further later.

I'd like a planet with a variety of biomes, inhabited by many creatures, much like Earth, but life on this world took its own path, with different plants and animals (and perhaps a different distinction than "plant" vs. "animal" to begin with)

There should be at least one sentient species represented in a wide variety of cultures and societies. They should have complex interactions with each other, and other species on the planet, and resulting from that, their own needs and wants and fears which ought to be relatable in context but may at the same time be strange, unusual, and, well, alien to humans.

But let's start at the beginning: Can you give a few broad, interesting biomes and how they might exist in their "wild" (pre-sentient) forms vs. how a local sentient species might have altered them over the ages?
While doing so, it is important to consider the solar system that planet is a part of, as other objects of the system, especially ones that are very close or very massive, may have a significant effect on the planet and its biomes.
