, next year is probably JWE3,
Not probably, it was already directly confirmed by Frontier themselves that the new Jurassic game was going to be the CMS game being released in the next FY.
Also I see there's no way frontier will miss the opportunity to add Planet Aquarium.
If anything the fact that water parks did not come as a separate game is further confirmation that it's unlikely that Frontier is going to go for an entirely separate aquarium game instead of adding it to the sequel of Planet Zoo. Why would Frontier even go for a separate game? It doesn't make sense for them to do so.
First reason is the most obvious one of all, your current Planet Zoo audience for the very most part wants aquariums to be added to the game instead of it being a separate game where they can combine both. So why would you want to risk upsetting a group of people you want to come back for your next game?
Second of all, unlike with zoo, there are already a bunch of major competitors on the aquarium game market. You have Megaquaruim, Aquarist, Aquarium Designer, etc. There's already plenty of games out there for people who want to design their own digital aquariums (from a single tank to a full fledged aquarium) with a lot of deep management that Frontier's CSM usually don't tend to have. So again, why go for the risk here?
The safest financial bet here is to make aquariums a major selling point to a Planet Zoo sequel. Yes, it will be simplified in concept and it will not be to the level of deep management that the other aquarium games have; but it will have the rather unique selling point of it being in a very creative game together with full fledged zoos. And that's a part of a market that hasn't been properly targeted in years, so that's another win for Frontier.
Frontier is going to play it safe for the coming years, they communicated that very clearly. That's the best bet for them right now, and that means that their choices will reflect that. I wouldn't count on a Planet Aquarium game if I were you because of that.
We literally didn't need a second African Rhino...
You can literally discuss this till the end of time, but what "the game needs" is only objective based on your own subjective criteria. It's so incredibly pointless to argue whether or not an animal is needed.
Some people want as many visually different kind of animals as possible, other people want as many common zoo animals as possible (me), other people want as many subspecies as possible, etc. etc. We all have our own criteria that makes us judge whether or not an animal was needed. That's fine. I'm sure your criteria justify your lack of a need for a black rhinoceros just as much as my criteria do justify the need for one. That's all good and all fine.
But to go over the same "we didn't need animal x" argument over and over again (talking in general, not you specifically) is one of the most tiring things in this community.
