@Scobre idk what exactly in "there's still content they can add to the game after University, there's a ton of ideas on here and elsewhere on social media" gave you the prompt for that rant.
I said nothing about HOW things were implemented (and honestly, the fact that there's so little occult stuff in the game just tells me that there's room for more). I only spoke about magic, not about occults in general too so I'm not even saying there's too little or too much, that's a whole another conversation. I'm also not talking about how much the game can change.
Bottom line: you hate TS4, I don't. Each to their own. Just as I think there are still a lot of themes to be added after University, which is why I answered your question: what more can be done in the game? Tons. Things brought back from previous versions, brand new things that were not in the games before. That's it, simple answer to a simple question in one specific post.
