You're probably right, Atarah. Still, I find myself running all three games in paralell, with multiple tribes in 2 and 3. I check in morning and evening, and work with my tribes to keep them on the right track, but otherwise leave them to their own devices.

I'm generally not a fan of casual games, but the VV series has me trapped. I have other things to play when I can't get out to blow a couple of hours, but I keep coming back to 'my' villagers.
