As I said in the post taking advantage of something does not mean it is an ideal situation Kolikokoli, it means that is what they have to work with so might as well as use it. You misunderstood my meaning about the zoo terrain, what I meant is that the terrain still has to be modified and worked on in order to see the zoo plans go accordingly. Look at Tiergarten Schönbrunn as an example, a magnificent historical zoo that has a very strange layout because of the terrain they had to work with to create exhibits, a complete area of the zoo is somewhat challenging to get to.
Prague Zoo would be another example, and one that I'm professionally very familiar with, and definitely one that has created a number of challenges for its administration in the past, here the space allocated for new exhibits had to go through a number of alterations and plans adjusted accordingly.
There are cases where challenging terrain does work for your advantage, that is the case of the Taronga Zoo, as part of what makes that zoo incredibly special is the many levels and terrain changes it has set against the dramatic Sydney cityscape backdrop. One of my favorite zoos because of this by the way.
In the U.S we have a perfect example with the San Diego Zoo, a zoo that has used what otherwise would be a deterrence to built anything in a terrain dominated by canyons and mesas, as an advantage and adjust to the situation. Their last completed project, African Rocks, was developed in one of the most challenging areas of the zoo, it was also their most expensive exhibit up to date at a 68 million dollar price tag. Where do you imagine a large portion of that budget went? Terrain modification as it was necessary to create their modern vision of a multi ecosystem African exhibit exactly as planned.
I'm not against dramatic landscape changes in game or real life, I think in most cases if done correctly it looks amazing, in fact I have participated in a number of real life projects that had very significant variations in terrain. I just rather do it myself than have the game provide it for me, when I will have to end up changing everything. I do understand that many players just want to play the game, and the quicker they built a zoo where to play in the better for them, that makes sense.
Again with game performance I just do not see it happening, the game is already taxing as it is unfortunately. I believe that is the same reason why their map backgrounds are so simplistic, many wanted beautiful and complex backdrops, detailed cities etc, definitely something I was interest in, until I was informed that it would hinder performance even more.
