Fallout creator Tim Cain explains why adding everything ruins games.

Legendary game designer Tim Cain, known as one of the creators of the original Fallout, shared his thoughts on common mistakes in game development. He believes the main problem with many modern projects lies in the developers' desire to cram as much content as possible without considering the necessity and compatibility of the elements.

Cain called this phenomenon a "designer's hole," which can ruin an entire development project. He recalled a colleague's wise saying: "A game that has everything is about nothing." This rule applies to all aspects, from the plot to the game mechanics. When developers try to mix aliens, magic, telekinesis, and detective work into a single story, the result is rarely successful. The same thing happens with mechanics: crafting, base building, or object destruction are added simply because it's trendy or "someone else did it," not because the game truly needs them.

The game designer emphasized that every decision must be justified. Before adding an element, the designer must ask themselves: why is it needed and how will it impact the overall experience? Without this approach, the game risks becoming a disjointed collection of features that only interfere with one another.

Kane also noted the mistake of developers pre-programming expected player reactions, attempting to force them into rigid frameworks. This approach can only work in highly linear projects, but in most cases it only limits freedom and ruins the experience. He has previously criticized the industry for its desire to please everyone, which leads to wasted resources and the creation of impersonal products.
