I purchased and downloaded it over a year ago and (whoops) my PC did not meet the minimum requirements. I just finished upgrading my PC (which was so much fun; I LOVE doing stuff like this myself ); a new processor, a dedicated graphics card (Ouch! $$$ It was a TERRIBLE time to need to purchase a graphics card!), a bigger power supply, more RAM. I have been installing and tweaking everything these last few days and I haven't yet attempted to load/play Planet Zoo. Everything that I have seen about it online makes it look look absolutely stunning!
