I think stealing builders will still be a valuable pastime, it just will require continuous effort instead of a cheap one-time snatch and grab. Good point about pillage-repair though; you'll need to think twice about pillaging.Well, this should completely nullify the pillage-repair exploit in Civ V. That alone is a good thing. I guess we'll see how it works. I will miss worker steals though; I thought it was a good way to represent a very real part of history. Rome had plenty of slave labor supplied by defeated enemies.
Being alpha, the numbers are sure to change, but the video does show the relative costs in the production menu.Do you think that the builders will be a lot cheaper compared to workers?
Spoiler :

Noticed that, not sure what to make of it. They may be playing fast and loose with some of the Civ V icons as placeholders.On a sidenote, did anybody wonder what that improvement with the civ5-academy icon was that the builder could build?
