I don't think there will be a Zoo Tycoon 3. There's not much to improve, except some annoying bugs. The graphics are good and I like Zoo Tycoon 2. I also don't want to buy all the expansions for Zoo Tycoon 3, I'll probably won't even be able to play because my computer would go soo slow. Oh ya. Something else they could improve if there was a Zoo Tycoon is make AI smarter would be cool. But I doubt Microsoft and Blue Fang would make another Zoo Tycoon.
