I still don't think we fully understand each other. It's not the park that gets filled with festival stands. "Park" is a venue type that can get assigned to any lot by the player. Nothing whatsoever spawns on lots, only ever on the shared space between lots. This may sound like nitpicking to you, but you'll need to understand the difference between open world space, lots and venues as well as between festivals and holidays when you create your concept and subsequently make your project pitch.
My viewpoint is not based on technical limitations, but on immersion concerns. You wrote that you are a roleplayer, so let me draw you a mental picture. Imagine your group visits a weapons shop and instead of saying "I bought a new equipment book", your GM makes your character play out the purchase of the book. Not the new weapon. The real life book. Then you use your phones to order that book in the middle of your gaming session. Likewise when you get to choose what new region to explore, the questgiver offers your character adventure modules. That's the level of immersion breaking we're dealing with here. The problem is not the buying and selling of cc on principle, that's fine (personally I'd even accept microtransactions). But it happening in LIVE MODE is what's going too far.
I guess we are missing each other conceptually. I just used the park example because during let’s say, Seasons. Events occur at the park and certain activities are found during certain times of the year. Let’s just say at the spring festival there would be stands for purchasing items like “corndogs”. I wanted to open people up to ideas and get their input. It seems everyone is going off the concepts that are currently out there and picturing a stock market scene with everyone screaming, buy/sell. Trading places example. A virtual marketplace does not have to be overloaded, it can be along the lines that are already in the game. I understand about the spawning concepts because the only way for shared items would have to be in an online interaction. I didn’t get your guns/book analogy though. Sims 4 architecture have sims going to different worlds. In the retail stores, you can purchase clothes and you can purchase food in the restaurant venue. This is a separate world from your game. I know with millions of people creating custom items from shoes to plates of spaghetti and meatballs it can get crazy. I wanted to put the idea out and get input.
