What I personally love of the Eberron setting is this :
It mixes typical - although not medieval - fantasy with a variation of steampunk - keywords: the Warforged Ones. Lightning Rails. Sharn alone. Airships. "Magotech" is the entry word for that at TV Tropes.
It places things & themes known from the classical fantasy settings into a new environment. Xen'drik is deep jungle; Sharn is deep town space, almost "urban fantasy" in itself. But, Eberron is even more : It is one of the few fantasy settings with pirates.
I*d really like to see an offline sp RPG for that setting, because it still feels kinda fresh & new to me. And underrated, but that's my very personal opinion.
The only Steampunk game I liked - although I didn't play it through - is Arcanum.
