Which faction do you like the most?

I would say "dwarven crafts"... as for artifacts, I wouldn't be so insistent, especially since "elven" (not to mention "mage magic":) ) magic is stronger than "dwarven" magic, and when creating an artifact, I think enchantments are more important. Also, we shouldn't deny elves their blacksmithing skills, but we're more likely to have problems determining which world we should be focusing on.
