I don't think I'll be able to play this game again for several years, but it is awesome. I've played through four times. Out of the origins I played, Dwarf Noble > City Elf >> Mage >>>> Dalish Elf.
There is some really great potential to completely fuck up the world in the epilogue. My favourite is
creating the Golems AND choosing Harrowmount.
Bhelen is a little more restrained with the Golems, but Harrowmount goes awesome crazy. He cuts off contact with the surface, and implements harsh traditional laws. He crushes the ensuing rebellion of commoners with his merciless Golem army. Seeing the toll that maintaining this force is taking, he declares that no more dwarven souls will be put into the Anvil... instead electing to conduct covert raids on the surface-dwelling races, stealing their people back to his underground lair to turn them into subservient killing machines. When the humans and elves eventually learn of this, they declare war... which Harrowmount, of course, fights with his MERCILESS GOLEM ARMY.
Note that 'discover all endings' only refers to the very end sorta stuff... I can think of a few possible variants (plus the two other Origins) that I haven't seen.
