Serenia
Anyone else get hopelessly lost in Serenia? It's a beautiful age, one of my favorites in the series, but it took me an hour to find the proper offering AND get it to the right Spirit Guide. And this was when I was playing the game for the second time! Zip mode helps a little.
This is nitpicking, but there seem to be a few anachronisms. The game is supposed to take place around the 1800s (I think), but Yeesha says "cool" and one of the Protectors says "This is so not good" when Sirrus trashes the harvester. And Achenar says "Screw up". But who cares. The game is awesome.
