The sims has always been pretty quirky and cartoony and honestly I wouldn’t have much interest in the game if it was more realistic. I have the chaos of real life for realism. In a video game I rather have some quirks and whimsy but to each their own.
Personally the only quirkiness I couldn’t get behind was the werewolves. (I wanted to like them since I like werewolves in a lot of other media but they are just too goofy in the sims 4 for my liking so I didn’t buy the pack) but that’s a personal thing on my part.
