Well - I wouldn't call it a buggy mess. It's less buggy than other previous releases, so I don't think you need to worry too much.

My opinion: Again a decent world, but unfortunately quite standard - some nice details, but really nothing breathtaking. BB/CAS items are good. CAS items are remarkably numerous. The Love Struck gameplay is a bit out of tune. We got the turnon/off feature which isn't a big difference from the already existing likes/dislikes (but it's onesided per sim, which might be a difference). Romance satisfaction tuning is awful: it decreases so quickly that Sims would starve to death because they don't have time to eat in addition to all the flirting needed to keep the romance level up (I guess that's not a bug). What's also remarkable is that the whole pack is quite spicy or adult. We got a love hotel, new woohoo spots and a lot of hidden things which might develop according to the individual playstyle. I like it, but of course it's as always a matter of taste. Finally I would recommend to wait once again until there are special offers for that pack. What you get doesn't justify the original price tag.
