the impression he’s talking about more than one pack
FY24 ending in May allows for one more pack in Easter as well.
Planet Coaster finished up in June 2019, so there's also a possibility of one last DLC in June I suppose.
the sims 4 has sustained itself off dlc for 9 years
The
Sims 4 exists under such wildly different circumstances that it's incomparable. The lifetime of
The Sims games is extended by official support for modding, not to mention a core fanbase considerably larger than
Planet Zoo's. I think people on this forum especially often forget how absolutely niche park simulators are. JWE has brand recognition to help it along, but PZ doesn't. We're a small corner of the gaming world.
Definitely better off comparing notes with
Planet Coaster. That is our frame of reference. We've already passed the lifespan of PC so we're kind of squeezing everything we can out at the moment, but, if we're calling it "doom talk", then "the end is nigh, woe unto us all."
Edit: PC ran from November 2016 with its last DLC released in June 2019. That's only two and a bit years of life. PZ on the other hand released in November 2019 and we're currently nearing November 2023. That's four years. If we optimistically suggest that the "last" pack will release in June 2024, that's four and a half years. Pretty damn good.
Prepare for the worst, hope for the best.
