World modeling: unique mesh or different pieces?

    Hi guys, this is my first thread on this forum. I'm a 3d modeler for some years now, I've modeled something for games but anything important.
    Now I'm going to model a world for an open world game and I had a doubt, the terrain should be a unique mesh or different pieces?(For example street as a series of planes and the sidewalk as another object...)
    I put it in the getting started section because I think it's a quite basic thing to know ;)

    The choice is up to you, and your personal workflow. However, each separate Mesh accounts for one draw call. Meshes that can be combined should be. Unity batches meshes below a certain size, but the size is very low.

    You also have the UV's to worry about, so a road could either be painted right onto the ground or made in geometry. Each approach has its advantages.
