Very unoptimized run. I realize partway through that I need five research labs and not four, I got borderline bad challenge luck, I misunderstood the endangered species release achievement, I forgot to get rid of the dinosaur after getting the rampage achievement, and in retrospect I think the 20 endangered species achievement might actually be viable for the end of the run. Not to mention the myriad of accuracy issues and general sloppy route. I place foliage and rocks to up the Educational Habitats part of Zoo Fame. I believe higher star animals help fame as well. I get the 10 Supers achievement at the very start to give my Paleontologists more time to get the 1 Star fossils for a chance at the All 1 Star Fossils achievement. The weirdest optimization is the use of the Extinct Education Center, which has four achievements attached to it. By adding an abundance of Play Dig Pits, this achievement gains progress passively while you do everything else. Setting the zoo price to free leads to a lot of guests coming in using the dig pits accelerating the process. I think setting the prices to low also helps guest happiness but I'm not sure.
