All I've ever heard about planet coaster is that it's an unfinished mess that got half-finished with hundreds of dollars of dlc, so hearing another is in the works is kind of like.....
Maybe finish your first helping before getting another slice of pizza?
Man, I really want to play some elite dangerous, now...
Ehhh. the game is coming up on 8 years, it's definitely time for engine upgrades. Also the majority of DLC is themed packs (ghostbusters, back to the future and the like) with scenery, a single ride, and a single coaster. I wouldn't consider it half-finished.
Planet Coaster 1 certainly wasn't half-finished. The developers actively listened to the community and constantly made free improvements for years after release.
Sure, it has lots of DLC packs, but none of them are in any way essential.
