Well I've got my first neighborhood that I ever made, several years old, already kinda fucked up due to me not knowing what to avoid (at least half of its population has been deleted over time). I don't care for it and it would be fun to watch it blow up... Anything I can do to cause this relatively quickly, without corrupting the program files?

Feed him to the cowplant.

Hmm I'm far from knowledgeable but isn't the cow one of those stupid uni npcs that keep their behaviour even outside uni settings, like the cheerleader? I think the only way to stop them from doing that is to change them in simPE and delete whatever makes them behave that way (I saw a post here a while ago that explained how to do that with the cheerleader, I'll see if I can find it again).

If you don't care about him and your sim being friends or whatever you could use debug mode to bring their relationship to 0 so that they're no longer anything, or you could use simPE to make them not know each other (sever relationship ties, memories etc) but that may be problematic... or just exterminate/kill the cow guy.

How do I do that? Should I use the batbox's Nuke option or do I delete them using debug mode?

Well I guess if I played TS3 I would eventually get used to their look,but I remember my shock when I first saw the promo pictures: Is that an improvement for their look??? But I agree, the sliders are awesome, you can customize pretty much everything without CC!

Thank you for the quick answer! I have heard of ACR before but was too afraid to use it, I don't want my sims flirting etc if I don't approve.   But I'll give it a try, it will definitely make things more interesting.
I should probably ask this over at simbology, but since I already started a thread: is it safe to just take the Inteen files out of the Downloads or should I do some kind of preparation beforehand? Obviously noone should be pregnant when i remove it, but is there anything else I should do?

BTW TS2 sims are MUCH better than the gooey TS3 blobs of pixels. One of the major reasons I haven't switched.

So I have been using the Inteenimater hack for quite some time now, before I learned of its kitten-killing abilities and its general tendency to conflict with other hacks. I don't really care for the teen pregnancy, but most of its other features, like the ability to use birth control or to control the sim's pregnancy duration (even with miscarriages) are pretty cool. Is there another similar, awesome-approved mod? i tried to search, but only came up with alternatives for teen woohoo and pregnancy.
