Wrath of the Ancients (2009)

from the designer's web page (this is a free download)

"Modernia" The greatest civilization this world has ever known, and they owe it all to you! You are one of the ancient (and Petty) gods who first brought gifts to the mortals. But the people of Modernia turned their backs on you. They don't believe in you any more ... They don't worship you anymore ... THEY DON'T PLEASE YOU ANYMORE! Use all of your divine powers, the proper timing, and a little luck from the Fates to forever DOOM this civilization ... just as you have so many ungrateful civilizations before it!
