What I like is how there are mods for so many different things. Stuff like textures and lighting is obvious, but for instance I love a mod that revamps rain storms. It makes them both look better and have splashes and ripples when drops hit the ground. Another guy also made it so rain wouldn't fall through awnings on buildings. And that's not mentioning the sound overhauls for it, and the lightning mods either! There's just so much new content that mods add, without being obvious about it, like a ninja outfit or being able to fly.
