Absolutely NOT this.
First of all, you can't compare not putting certain aspects into the game due to them being processor-hogs, to not making better/easier building systems in the first place.
Second, the only reason you saw many of the things in 1.4 was because a LOT of people were super unhappy after the Frontier Expo, and they complained about and critiqued what was shown. So Frontier made improvements accordingly. This argument that complaining/giving critique is somehow hurting the game's development is just plain wrong and 1.4 should be enough proof of that for it to go away at this point.
Lastly, it's not as if people are asking for that much, a lot of the systems they're currently using in Planet Coaster are just slightly upgraded versions of what existed 12 years ago in RCT3. On top of it, a lot of the stuff I suggested previously could be done with some simple line of code. Even I with very minimal coding experience can think of several simple ways of making what I suggested... There are so many ways to improve what's currently there without alienating the people who are already used to the systems.
First of all, Can you blaim people of not having the same ideas/view as you have?
If i would tell you, you can't do your job, that you are bad at it and that anything you do, can be done better; Would you become better in your job? Would you still like/love your job knowing people "hate" your work? I doubt it will will get the job done, it actually would make things worse, because such negativity tends to grow on people and can only result in making mistakes or failures.
Second, There was nothing added in 1.4 that was suggested by any "complainer" if you haven't noticed that, take a look at the update notes.
They did add the constructive comments of a few core community members @ Frontier expo and some older suggestions made here on the forum by respectfull people.
Last but not least, yes Planet coaster = the upgraded version of RCT3, it uses the same engine but upgraded. (Cobra)
You claim you can make your suggestions work with a simple line of code? I'm far from coder, except some HTML and CSS perhaps. But i'm closer as most here to gamedevelopment, my brother actually is a gameprogrammer for a company in the Netherlands. I'v seen his work up close, and even the smallest features in games don't exist with a "simple line of code".
I know the hard work they do, i'v seen the devotion and dedication for the job manny times over, that's why I respect any gamecompany/developer out there.
Alot of them are far away from familie and loved ones, to do the job they love the most. Because it isn't something you just become, it involves hard work and education to become a part of any gamecompany.
So think twice before you claim they can't do their job, or have to endure 1000 of complains EVERY day that dawngrades their hard work, they are also human despite of what you think.
They deserve as much gratitude as anyone else for their work, perhaps even more, because after all, games are made for our entertainment, fun and happiness.
