Try Codex Arcanis from Paradigm Concept.
What you wanted:
- gritty or dark fantasy
Human gods who allow worshipers of all alignments, so the god of disease is a healer in one town and a plague bearer in the next and the god of oaths is also the god of demons.
The humans and their gods practiced genocide on the elves and the whole Dwarven race is cursed. And a whole nation of necromancers and vampires exists.
- lots of different cultures for PCs
Swedish, Polish, Roman, Mongolian, Ren. Italy, Lizardmen who favor Ranger class, and an African nation that likes clockwork.
- exotic and dangerous wilderness areas "where no man/orc/dwarf/whatever has gone before" (or at least for the past 300+ years)
The “Blessed Lands” are filled with ruins. There is a salt flat that becomes a sea once a year and many other places were abandoned after the Demon Wars. Humanity was saved only because their last true Emperor prayed for a wall of mountains to keep the demons out.
- high compatibility with "standard" WotC stuff (spells, PrCs, etc.) /B]
Check
- interesting "toys" (magic items, steampunk stuff, flying ships, whatever
