I'd expect Taoism inspiring philosophies and not religions. Being a way of life.
Hoping for some kind of animism too.
Religion is, more often that not, "inspiring philosophies" that are also ways of life. Religion is so much more than the abrahamitic religions and monotheism, or even theism. People really have to stop defining religion as the belief in a supreme diety (or several).
Religion, strictly speaking, doesn't even have to touch upon the supernatural.
I personally like this definition:
Religion is often described as a communal system for the coherence of belief focusing on a system of thought, unseen being, person, or object, that is considered to be supernatural, sacred, divine, or of the highest truth. Moral codes, practices, values, institutions, tradition, rituals, and scriptures are often traditionally associated with the core belief, and these may have some overlap with concepts in secular philosophy. Religion is also often described as a "way of life" or a life stance.
But also this, straight from the dictionary:
a set of beliefs concerning the cause, nature, and purpose of the universe, esp. when considered as the creation of a superhuman agency or agencies, usually involving devotional and ritual observances, and often containing a moral code governing the conduct of human affairs.
As a proponent of secular religion, I find your claim of religion requiring a extrahumanistic divine component to qualify as a religion preposterous, kind sir!
Edit: I, also, have hopes for religion in the game and the universe definately seems to lend itself well towards a animistic religion. Reinvigorating the world, restoring the world soul, or manipulating the primal spirits, or spirits that are angry at man's incompetence, hubris, or something along those lines.
