User blog comment:LostInRiverview/The Sims Wiki Monthly Question - May 2014/@comment-4568327-20140430234430

I think the difficulty for The Sims series is.... good enough. If you think maintaining your Sim's motives are a chore, just think about how difficult handling the AI. Or rather, the lack of AI. Bugs, glitches, bad choices, irritating decisions, repeatedly re-queuing interactions the player cancels, pathfinding issues, etc.

On second thought, I would probably say that The Sims should be less difficult. By that, I mean "Less Sims that decide to play computer games even when the carpool is honking outside".
