Seeing your settlement grow in size and become a bustling little town is definitely fun.
Everything from the architecture to the settlers hanging out the window pounding out the laundry adds something to look at. The detail afforded to all of the structures is pretty great. Whereas Heritage of Kings was good technically but offered up very little personality, Rise of an Empire has plenty of personality as the series has moved back to bright and cheery colors and cartoony characters with big heads and great animations.
It definitely helps that this is the most complete package we've seen in Settlers history.
