You will never find another life simulation game that's on the level of complexity that Creatures is. Creatures manages to have unparalleled depth, while masking the simulation behind a game that even as a kid I could enjoy. Make no mistake, this is NOT a virtual pet game. You will take care of your Norns, maybe even grow to love them. But you will be angry with them, you will feel pain when they die. It is a life simulation at it's finest. You don't just sit back and feed them. In fact under normal circumstances the Norns should be able to feed themselves. You'll guide them away from dangers, teach them right from wrong, play doctor when they're sick. And watch them grow. You may have to make tough decisions, like putting down a defective Norn, so he doesn't spread his disorder through the gene pool. It's a hard experience to explain, you have to see it to believe. When you do see it though, be warned. Creatures 1 & 2 have not aged well. While the actual art is still quite nice, the interface is far beyond the definition of ghetto. The GUI closer resembles that of a word processor than an actual game. But if you're willing to brave the interface, and get your hands dirty, you'll really find an experience that is unlike anything else you've seen before.
