I prefer the original for a number of reasons. While some features in the new game are very nice (such as the Jeeps and sky trams, elevated paths, guest mode), I prefer the more realistic look of the animals in the original game. Also, with the biome mode, it is no challenge at all to make a great exhibit for even the pickiest of animals, taking away the educational value. In the original, you could assign staff to particular types of tasks, such as repairing fences for maintenance, and that feature is not in the new game, not to mention that the staff seems a little dense in ZT2, since they can't seem to perform their jobs properly, ever. The landscaping in the original was easier in a lot of ways. I created several zoos with paths running into a trench beside a submerged tank (part of a combined exhibit), and this is practically impossible with the ZT2 landscaping methods. In the original, you could sell animals for money; in the new game, you not only can't sell them, but you actually have to pay to adopt them out (totally unrealistic!!). Then there is the issue of game performance. The old game never froze, dragged, or failed to do exactly what it was supposed to. The new one drags all the time, freezes regularly, and no solution offered helps with this, nor is it system-related, since my computer specs are beyond what is needed, there is plenty of hard drive space and RAM, and all the rest of the graphic-heavy games we have work extremely well. Since this has been an issue since the basic ZT2 package, and there is still no fix for the issue, I can hardly even play the new game. No contest on this one, folks! Oh, yes, an added bonus with the original was all the amusing and entertaining little cheats and easter eggs that were included, which are strangely absent from the new version. I rather like those, and they are sorely missed in ZT2!
