Is the Humble Bundle "Epic Environments" good?

This is the link to the humble bundle “Epic Environment”.

Attention, at least two packs are for Unity!

I have no idea what is good and what is worth it and if something is already free in the Marketplace from Epic or others.

So I thought I’d asked here if you guys think this bundle is worth it?
If so, why? If not, why?

I am full of fear to create anything with skeletons, you know, all these things you import in each an every book and each and every tutorial, because it seems to fricking hard to create a moving skeleton (and matching clothes?) yourself?

So, when I see a lot of nice assets AND different skeletons (is this the correct term anyway?) with different looks I am getting giddy, but the price is my problem.

So… is it worth it?
