Squick: We could focus on the gory aspects of the setting, but in regards to sex squick one particular thing is worth mentioning. In Shelzar, there's a construct based on the Gibbering Mouther monster, with certain...orifices in place of it's mouths. If too many people use it at once, it dies.
Too Good to Last: The Scarred Lands was a very diverse setting, and with over 30 supplements, very well fleshed out too. Another company did eventually get the license for it, but so far they've only released a monster manual updated for 4th Edition. How much they'll expand the setting remains to be seen.
