Yes, if theaters, casinos and other new buildings ever appear in the Planetbase game, the game will reach a new high level and will again become very interesting to the community of players.
I hope that someday we will see the continuation of the game :-)

By the way, here in this thread of discussion on the forum, one programmer writes that he is working to add such new buildings as casinos and theaters to the game https://steamhost.cn/steamcommunity_com/workshop/discussions/18446744073709551615/1849197902670717252/?appid=403190
I really hope that he succeeds! :-)

Dang I forgot... it's been a while.
I wasn't rushing at all. Just trying to keep the mission going as long as I could.
This mission made me want other buildings like theaters, casinos, and other stuff that would attract Space Tourists. :D

@PestMastah Thanks for the information! Interestingly, in how many days did you manage to achieve the goal with your strategy?

You should see mine.. I usually tear down the smaller bio dome and just build a bigger one. I add two Herb plants (herbs sell for 10 each) and this helped get me the ca$h.
I also add a bar, fitness center, and larger bunk attached to a small oxygen. so I can rent out to tourists for more cash. Try it. :D
