Criticism is something different than complaining that you have 42 dinosaurs and SOME of them look a bit similar. Lack of fountains, benches.. etc is criticism. what you are saying is sounding like a kid in the candy store not getting his way. As for telling the difference between, the Dinosaurs. I can do it perfectly fine and have no need to go into lengthy detail on here about my knowledge of different dinos, if you are interested I suggest checking out http://www.nhm.ac.uk/discover/dino-directory/name/a/gallery.html
You're entirely missing the point as pretty much always. Take a step back and really think about what I've said and how you're responding to it.
