I seriously think it is too soon to think about a PZ2 when the game is so new. But yet everyone keeps talking about it because they hope it's better than what we have got now. But sure that tells everyone how much PZ is lacking? The game needs to do more for me to buy a number 2, if not then I will be like you, furious and ripped off. PZ within itself has so much potential.
I surely hope that we get flying birds at the least and not be forced to buy a number 2.
Because if the sims4 can keep pumping out new packs about a life simulator, I can't see why PZ can't do the same.
I guess what I am trying to say is that if PZ does end this year then I will be extremely disappointed and won't buy the second one unless it's like on sale or totally amazing, great gameplay, has better packs than PZ does now, a better game engine that supports big zoo's that are highly detailed with at least 3,000 guests, better animal behaviours and personalities, birds in base game (<- birds aren't important but would be nice) and maybe small fish but I doubt they would be added
