I should also add that: I think artifacts should be more valuable (in other words, do more). As it stands, even with the new artifacts, it doesn't really pay to search for artifacts. In online play, you NEVER seen anyone 'waste' the money on them.
They could be an exciting part of the game, that is way underutilized because they are simply not worth it. Even tho they introduce the element of luck, making 1 of the 12 artifacts VERY valuable, would motivate people to search for them.
Finally, I always thought they would be an excellent way to continue telling the story, the lore, behind the game. (Or even be part of a campaign mode, along with tailored diplomatic missions, and unlocked maps as you progress).
