I was reading through this thread and the last few posts got me thinking. TS3 does seem to be more kid friendly than TS2... especially the romantic interactions. Teens don't have as many as they used to, and there is no "goose" interaction, which I always thought was kind of cute. Makeout is very tame and so is woohoo. I'm not complaining, it's just something I noticed when I was playing.
They really, really, really need to fix the borked routing. The foot tapping is driving me batty. I also find it kind of irritating when adult sims throw a tantrum when someone is sitting in a chair they want when there are 5 other chairs to choose from. It's like TS1 all over again.
