That's ok-hey your moving to my state!
Anyway, I think that you should put in compatable biomes for each species, minimum cage size for each species, and maybe some tips and tricks for campaigns and challenges like you said. That is all that I would really need, but some other stuff would be cool like pictures of species that you can't get without creating them in the research lab. quaggas for example.
