High magic, rule of cool physics, Po:, but those points are huge, complex cities, the tone is light and fun, and absolutely nothing Lovecraftian.
Basically, Eberron didn't go too far enough with dealing with the actual fun and exciting part of fantasy: the fantastic bits. More magic, not rare and 'special' grandma's heirloom figurines. Thrilling action, not Earth physics as imagined by people who think Earth is way more boring than it is. Thriving and lively instead of oppressively grim (how can the Eberron setting be so fun but the novels be so... ugh?). Interesting mosnters instead of HP's spitup.
