Would 1% lower Welfare really be that bad?
I guess I'd ask if 1% inaccurate biome tags would really be that bad.... Assuming that they fixed everything else that wouldn't negatively impact previous game play, including the exhibits and adding appropriate biomes as suggested in these forums (which I support), but simply avoided the step of deleting biomes from the few habitat animals that are in question. What do we truly gain by those particular deletions that is so game breaking or reality breaking if we leave those few as they are? Are players (or science itself)
really relying on zoopedia or the in-game biome tags as if they were unimpeachable educational guideposts? I'm not sure that guests even take information at real zoos that seriously or read that closely. Informative and entertaining, yes. A good intro to get you to go home and learn more, yes. But the type of thing that you'd cite as evidence or rely on? I don't think most people use them that way in real life, and even fewer would rely on a biome tag in a video game for that.
But to answer more directly, I think the impact really depends on how people play, and what choices they've made in reliance on the existing rules/guidelines. If you've worked hard and prided yourself on building habitats that truly maximize animal welfare (not just get them moderately happy or even extremely happy, but truly are always searching out ways to get them to 100%), then yes, having a retroactive rule change that undoes that work seems like a bit of a deal. And if the game is truly about conservation and animal welfare (as some claim), then making a decision that knowingly
hurts animal welfare in the game -- even by a small percentage -- seems to be counter to the developers' stated aims and the goals that some players have been faithfully trying to achieve. Why should players continue to care how happy their animals are in-game, if developers decide to go out of their way to intentionally make them less happy after the fact? Why spend time trying to make animals happier, if the attitude is simply that "well enough is good enough", or that the percentages don't matter?
Similarly, I imagine that there are people who are on the other end of the spectrum -- not trying to get them at 100% happiness, but instead working on their own designs -- who have made compromises to their creativity so that they get their animals just barely into the green (or just into the orange/yellow, or just above the red), for whom a 1% difference is enough that it could bump them down.
Or people who have constructed fully themed zoos based around the biomes, using only the animals, plants, and decorations appropriate to each. A change would mean that they either have to remove those animals from the zoo, redecorate in a way that ruins their motif, or take a hit to welfare (including welfare's impact on breeding and donations). This could be true not only of multiple zoos, but of multiple sections of different zoos. Like if you designed your zoo not around continents, but rather around biomes. Imagine going into the temperate section of the zoo, and suddenly every third habitat is off theme. After all, people use the in-game information not just to build their habitats one by one, but to make larger decisions about how they've designed their zoos and sections.
Imagine someone playing on hard difficulty franchise mode, complete with refunds, who doesn't read the update notes and can't figure out why their functioning zoo is suddenly going bankrupt. A fall of 1% animal welfare could drastically impact guest happiness and lead to financial problems that reverberate for quite some time. Or someone in the middle of one of the challenges, where you have to get animals up to a certain level.
I fully recognize that these are all hypotheticals, and that they definitely won't impact every player. I suspect that many won't even notice. There are probably even habitats of mine where I won't really notice! But that only begs the question: How badly are we willing to hurt the 1% of players who followed the rules and for whom it would matter? How bad are they that we need to lobby so hard to make sure they get punished, even when other non-punitive solutions have been suggested?
