Thank you for fixing the link :)
I wouldn't mind if Attraction is tied in with Likes/Dislikes. They would have to reconfigure it to make it act differently, but it's possible.
I just want it to be a real attraction system, so if your sim doesn't like sims with brown hair, they won't be able to romance them at all. No more romancing everyone. If sims aren't attracted to someone, then they shouldn't romance them at all.
I've been using Wonderful Whims for awhile, and I do like it, but I don't think it's strong enough. I would like the game to come out with a new attraction system that actually effects the way your sim interacts with other sims.
