Suggestion: COMPETING CREATURES --- I would like to see a way that a user could clone a creature and modify its clone and then test the fitness of both at the same time, with a way to switch back and forth or cycle through the creatures intended to compete in the same activity. Offspring would generally be of one or the other, usually avoiding breeding of neural networks between different body types, but if enough of the parts could be matched up to consider them structurally compatible with each other, their bodies could even be occasionally be included in the process of breeding, producing offspring with, potentially, physical and mental features from both parents. Perhaps the most fit of such hybrids could even be made available in the creature building area.
