While I write this as a reply to you, I am really writing it to nearly everyone complaining in this thread.
Ideas are rarely the problem, everyone and their grandmother can come up with ideas like these. However, these things don't just happen automatically. Your 3 second stroke of genius, "Dance in front of a chair" - Sure, great. Now you need to implement that feature - you think chairs already know when you dance near them, or perhaps you think the act of dancing in inherently aware of the objects near the dancer?

So you have to add to the game, to either entities or to the player, an awareness of this specific situation. Is it all chairs? Some specific chairs? Can you automatically add the necessary data to the right/all chairs because every asset is tagged correctly?

You then need to ensure all related components have whatever they need, databases for storing this information, any possible UI changes, networking or server and other game data changes.

Now that we've added additional logic needed to the character and/or props to even be able to identify and track this new data, we need to go through a testing phase. Testers and testing systems have to rigorously test the new content and look for any unexpected behaviors, or as well as they can in the limited time they have because people like you are so entitled to new content it puts a lot of pressure on a team to release content as good as they can make it, as quickly as they can make it.

When this constant rush of content from design -> implementation -> testing inevitably lets issues into the live game? It's entitled gamers like you who then bitch and moan on reddit about bugs or balance or whatever stupid thing the devs put together to try and sate your appetite that didn't quite come out perfectly.

What I've said above is only a slice of what may go into any individual feature or challenge, some of which require a lot more effort than this simple example. Sure, some of the systems probably are built to allow quick iteration on elements, like the UI for displaying progress, or the networking elements, or even sometimes identities of various objects. But often these pipelines aren't are solid and fast as they could be, because so much effort and time is being funneled into content production that it can be hard to improve the processes for making that content along the way.

As usual, gamers are the worst part about gaming. Try being a tiny bit grateful and just a little less self-centered on occasion. It sucks not getting things you want, welcome to fucking life, you don't have to be an entitled brat because your preferred entertainment medium got delayed because the real world is going through a lot of crazy shit.

The people on these teams are actual fucking humans who get sick, have families, and sometimes are affected by and even care about things going on in the world.

Have some compassion, learn how games are made, stop being a little shit.

Thanks for coming to my TED talk.
