Interactive Skeleton mapping questions

Hey guys: super noob here.

I had a question about interactive skeletons in the unity engine. When I talk about this I am referring to the kind of mechanic that is in the game “Spore” in which the player is able to edit and create a character model and then have that character model able to move around with animations and such.

From the tutorials I’ve looked at here it looks like this kind of mechanic would be difficult to implement and animate. I was wondering if this kind of mechanic would even be possible with the unity engine?(I’m sure it probably is.)
Would a complete noob like me with no coding experience able to create something like this with enough practice?
I would like to know if this even a realistic expectation as I’ve heard from other places that I shouldn’t even think about things like this until I’ve tried making simple things first.

Here is a great thread that will point you in the right direction.
Not suggesting you start out with pong.
And there are a couple other threads here on the forum discussing spore creature creation ‘like’ content development.

Thanks alot man I appreciate it!
