What'd be interesting is if they added a sense of realism or at least a setting that enforced a few other restrictions. It'd be interesting to see what you ended up evolving. Things like metabolism limit the size and shape of creatures but I doubt this will be a feature since it would probably be considered too restrictive 
I also wonder whether they'll have support for subterranean, airborne or arboreal species.
