Want a bit more lore? There is an extra loadscreen file they left in that has a nice and sinful Vasari domination feel to it, and it says it's Beta 4 (or 3, I forgot)
It also goes on to explain how there are "placemarkers" put in the game, possibly before they made all the meshes for each faction. Oh, and there are 2 pictures of a fourth race in all the playerpicture files, if you want to know some of the other directions they could have went (I'm sure that this board is packed with people who have inside info on all that early stuff, and are probably sworn to secrecy on all their early "mistakes" in presentation)....
don't ask me though, I missed that part...
