The franchise already knew (from years of Simmers discussing) what was wanted from the series. That was the (touted, albeit likely untrue- since the focus is more on making a pile of fast money) goal of TS4; a much better working model of TS predecessors. The franchise knew about all of the various issues (game breaking), such as bugs, lag, and always adding more packs. They also knew that most players engage in legacy play, and have long running storylines. They also knew that people like building, design, and creating their own (tuned to them) Worlds.
So, going into this 4th installment, with all of that knowledge, the knowledge is that there will be additional packs, items, and ongoing additions.... Before even announcing (and by announcing they added pressure to themselves to quickly bang out a product- because they over-hyped it before addressing key issues) that they would be attempting to design TS4 they should have asked themselves: How can the team make those things knit together, and work as seamlessly (as possible)- without a multitude of issues? First, and foremost, is that they must ask themselves if it (really) is doable. That would mean that they must (1) develop all those packs beforehand and ensure that they do not conflict one another. Or (2), with each new pack, test, test, take time, and test again, all of those new mechanics- to ensure the final products all piece together in harmony.
