I like kweping some stalls like chief beef and some others like that but wNt realistic stalls too. What im really hoping thhey do is put a building syatem like sims 4.
John Laws already confirmed is piece by piece building on the Q&A. The Sims building system is great... for The Sims types of homes. Same with the road building system and water wonky physics is great for City Skylines, but what Nvizzio is doing coping it 1:1in RCTW (actually with the help of Colossal Order as they said) and surprise, we discovered in the beta that both of them worked badly, not because they were done wrong (they are 1:1, probably copy pasted code directly from Colossal order), but becuase they actually dont work with a theme park game, where both of this things need more finesse as a theme park simulator has to be more detailed than a city one were all is done on a bigger scale.
He also added its their OWN piece by piece system, that they gave it a twist to make it better an more enjoyable. What this means, we still dont know. It could be a copy chunks of rooms and modular building system similar to what The Sims 4 added. That would be an excellent thing to add to the piece by piece system, but copy exactly something from another game, to shoehorn into a game that works radically different? Well, yove seen what happens there with the RCTW beta.
Just a good example why the Sims building system would be really hard to work out for the type of complexity RCT3 and Coaster Planet have:

Those types of walls that use custom scenery in RCT3 would not work with the Sims building system. Same with the sloping level of any roof, when in RCT3 you could do it by hand and the size depended of the custom scenery you downloaded. Doing crazy design in the sims games is super constricted. Its great for building normal homes, but not much else, mainly because it use prestablished heights, a limit you didnt have with RCT3 custom scenery.
I actually really like what RCTW is doing, but I also trust the Frontier guys. They do know what they're doing. With Planet Coaster, I just want to be able to build realistic parks. I'm not asking for no charm, no artistic liberties, or no style. I just want to feel like my park could exist. I'm concerned that it will feel like Thrillville where it all takes place in its own cartoon world. Once again, that's not an observation (So far, everything from Planet Coaster looks pretty good), it's a slight concern I have. I don't want this game going completely to the cartoony side. That's all.
If its not an observation, because everything they showed doesnt even look similar to Thrillville, why do you have that concern? Im sorry, but I just dont understand. I had lots of concerns 2 weeks ago with this game, until the dev diary and John Walls Q&A were done were it resolved all the concerns I had.
Also RCTW its in a delicate state now, were it just flat out doesnt work properly (and, even if dont like saying this, it probably will be borked even when it releases). Why are you happy with them? Nvizzio is not at fault there of course, the poor souls had only 6 months to make a game, and it shows, but why eat atari's lies? My concers for that game are huge, and the art is the least of its problems.
