As a vegetarian in real life I really appreciated this trait in the Sims 3. The Sims 3 had a lot of traits that didn't really feel like they had much impact, but this one changed everything a sim ate. It also had really good interactions with different types of sims- especially the ability to create vegetarian Vampire and Werewolf sims, which I always had a lot of fun with.
I'd love to see it reintroduced into the Sims 4.
So, sure. I support this.
