seventh Cross
If you’ve ever wanted to play god and develop your own unique creatures, right down to the very fabric of their DNA, then Seventh Cross is a game you should take a look at. An almost infinite number of chimeras can be created and you must guide them from slopping about in primordial swamps, to embracing the bipedal intelligence we see today. A true survival of the fittest, even Darwin would have a blast playing through this.
