David 'Rez' Graham, a former developer at Maxis, reworked the AI for The Sims 4 during its alpha phase. Faced with unconvincing NPC behavior, he rewrote the core AI logic in a week. This gamble resulted in more realistic interactions, aligning better with player expectations and enhancing gameplay. It’s a reminder of how developers can take bold risks to improve our gaming experiences. What do you think about such drastic changes during development?
