2 things would be really nice:
1) Various and interesting quests- not just go, kill, bring item.
2) Multiple choices. You can choose many paths. If you do one thing, it blocks some quests, but enables others. Something like that. For example- you helped one village a lot, with your help they defeated some tribe, so you can't make quests from that tribe, because they are dead.
3) Storyline and cinematics. Cinematics can't be too long. This is one of the worst things in campaigns and RPG's - too long and boring cinematics. I prefer laconic messages than whole essays in cinematics.
But you should tell something about your map Cyrus. What type of RPG will this be? Single player? Or like Defiance- loading/saving system, big levels, no plot.
I don't like RPGs like Defiance or Julien's RPG, because if I wanted to level my hero for looooooooooooooooong, I would install Diablo 2, Fable, Neverwinter Nights, etc.
If your RPG was like Blizzards Beastmaster's(what was his name?) campaign/RPG, and it had similiar quality, it would be awesome.
