Sorry to break the JWE2 discussion but I want to play devils advocate to the topic:
What if we can't guess the remaining content because there is no defined end to PZ yet and Frontiers road maps for DLCs only reach one full year?
Why does this community always assuming there is the countdown of doom running? I have yet to hear an argument for it that isn't "but Planet Coaster/ other games:!"
We are still talking about a game (niche or not), that has absolutely no direct competitor in sight. There is no reason to stop making money with it, as long as costs are lower than revenue.
Chiming in, that's a very good point there. We now know they will definitely be producing content "into" 2022 - that could mean one release or that could mean 3-4 next year, and possibly longer. Though of course the further out the less likely there would be new content then. I think we can expect at least one more content this year, maybe two, but at bare minimum that's two more DLC - one this year and one "into" 2022. I honestly do think we'll get somewhere between 4-6 more DLC, but....as you pointed out, what if there is no ending actually planned. What if they did release content not only for 2022 but 2023, 2024 and beyond. Personally I'm hoping we still get something in 2023 but I can't imagine something beyond that. But we don't know Frontier's plan.
Taking that into account, there are other zoo simulators are out there, but competitive, more realistic with the depth of management that Planet Zoo has, not so much at this time. I actually think Planet Coaster has direct competition than Planet Zoo does. Without a direct competitor, regardless of content Frontier would know that PZ would be the game we'd continue to play if we wanted to play a zoo game of this quality. While not having other options means that we're also subject to "whatever" they put out, there would also be confidence that sales should continue to be strong, so long as there is lack of competition. We've seen it's possible with a life simulator going on nearly 7 years now. There looks to be some competition to that on the horizon coming "soon", but so far it's not been released, and as such that developer has confidence that their game will sell simply because there is no other direct competition for their demographic to buy into. If there's not another strong zoo competitor we may not be talking just another year and a half. we may be talking another 3-4 years. Probably not, but if that were the case, I'd likely continue support.
What I do know is that I have about a dozen other zoo management games in my library, and none of them have come anywhere close to achieving what this game has in it's so far short life (or actually, what PZ achieved on full release, ha) Even if some of those have more animals than PZ, they're no longer the zoo game I play. And this coming pack isn't going to do anything to discourage me of that, that's for sure.
