I was calling this one of the best games I played this year the week it came out. But i got so damn frustrated trying to make my way through career mode with the bugs and the non-stop problems my zoo and animals kept having without even giving me time to keep building. I then switched to sandbox mode and sure it’s nice but not having a challenge sort of ruins the experience too. Then Trying to get paths to work on slopes too was driving me nuts no matter how straight and balanced i’d make a path it would just be a big mess. I want to get back into it and give it another chance with the patch… but currently enjoying other things now. Perhaps on christmas holidays i’ll try to delve back in
Patch is 5.2GB btw… Never understood how patches could be so damn big. Im guessing instead of tweaking code it’s just releasing a redone section of the game and ignores the other? if so… that feels and seems so sloppy
