Is it an inferior version of Civilization?
Actually this game ish much more chim than civilization.
Civilization ish easier to pick up and then become one more turn zombie, as the gameplay ish much more simple and straightforward. You don't need to master the chim-er aspect of civilization and can still have fun and win the game. Of cause if you can master the chim-er aspect like the max\min effect on population control, research, resource management etc will add more to the sexperience.
HoI ish more chim and difficult, it will still turn you into one more turn zombie but you actually need to study and master the game first cause the battle and strategy ish not simple and you can easily lose the game. So need to learn the game first otherwise you will be one frustrated zombie than a having fun zombie.
