I'm a rare breed in that I'm not too fussed in a completely overblown AI system for the dinos. I have no interest in the whole fight mechanic, but I'd like to see some decent pack interactions and hunting behaviour.
Thing is, it's impossible to get "real" with this. AI is programmed and has both boundaries and logic, real life doesn't, so it'll never be 100% accurate even though your brain wants it to be and will spot when it's not. The other problem is that a humans interpretation of what is "real" behaviour is both subjective and interpretive. Look at moral dilemma games for instance - would you save 5 old people from dying if it meant 1 child would die? A computer would save the 5, because 5 > 1. Humans would be more likely to choose the child because the 5 old people don't have a lot of life left, and people tend to sympathise more with children.
In short, all I really want out of this game is to be able to build my own park, put dinosaurs that I want in it, have them look awesome and act alive and then I want to go and visit my park, ride the rides, look out of the viewing platforms and marvel at the greatness when life finds a way
