I'm trying to get all the achievements without cheating. Got everything but Archaeologist, Space Ponies and Pop Idol. I should be able to get archaeologist and space ponies at some point, but I'm stuck on Pop Idol.

My current game is on a large random map. I have nearly all the planets. All the warp lanes are my color, and I still only have a culture percentage of 47 based on the graph when you quit. All of the the other players have 0. My one opponent is in danger of cultural revolt, so I had to turn off autocast on my 20+ revelation cannons or the game would have ended.

Has anyone managed the cultural victory legitimately? How?

Kind of frustrated with archaeologist, too. This universe had all the artifacts but one. Large map with high resources, you'd think it'd have them all.
