How can a game be completed, if price for all Sims 4 DLC (not included in original game) is ~1000$??
Jokes aside: the main game was completed. Now we are getting some additional stuff and polishing... Did you see how much content new content was added to NoManSky BaldursGate3???
Exactly.
EA and their The Sims games are insane!
Updates in form of bug fixes and polishing as you say.
For this game we could have considered it to be on Early Access before the developers & designers decided they were done with their planned content, as their Steam page say 18 April the game isn't completed.
If they chose to add more stuff after that date for other games that content would be in DLC or an increased minor build number.
Perhaps they want the space journey to continue but then the developers should release a version 2.
Baldur's Gate 3 was announced not to have additional content when the game was completed I think
