I'm also totally ready to buy this opinion. Could you talk about why it's awesome?
Read through the mod, it really says exactly what you get.
I would say 90% is purely cosmetic, and then there are a few gameplay changes, such as mounts and tweaks to perks and spells. Personally I'm not a fan of the gameplay additions, but everything that's purely cosmetic is a huge plus IMO. Vanilla came with so little variation that it made me sick of picking up the exact identical piece of weaponry or armor from every single bandit I killed before i hit lvl 10. This at least adds some variety, and then it's up to individual taste whether you like the cosmetic changes or not. The above example of Daedric armor isn't exactly my taste either, but that goes for some of the Vanilla gear too, so :shrug:
It also just combines so many other mods that you don't have to download 20 different ones to get the same result.
Give it a try, you can always remove it again, and it hasn't messed anything up in my game or causes any crashes.
