Zoo Limit (Major Issue)
Before you go all 'there's already threads about this' know that I'm making a new one because none of the thread titles properly get across what it's about. Hopefully a thread with this title will instantly get the attention of those looking here about this very issue, which has to be many, many people. It needs all the attention it can get because it truly breaks the game.
Simply put, the Zoo Limit must be increased. Especially on Xbox One. Way more complicated and larger games are running on 360 and PS3. There is no reason why the limit is where it's at unless it's a mistake, a very, very bad DLC idea (to increase it later) or just an extremely, and I mean EXTREMELY, poor code build.
It ends up breaking the game. With your guest rating comes guest expectations. You can build up your zoo and tear it back down over and over to somewhat control guest happiness but if you complete enough challenges that award permanent guest rating boosts (which sometimes are hard to avoid if trying) you eventually can't keep your guests happy. No matter what, it becomes impossible. Been playing this game pretty much non-stop since release and I've tried it all. The only way is to be able to add more, but we can't. Because of some weird, and extremely low, Zoo Limit.
Please, if you read this, add a comment so the devs see that this is a serious issue.
