yeagh.... the thief 1 zombies (go unconcious you maggot ridden ARGHH stop hitting me bad zombie bad...go dead damn it....what does it take to kill you.) were bad...the sound they made when you blew them up was nice though. The big mouth farting lizards were a joy to kill because they were just wrong too.

The servants in thief 2 also, and the builders children. The last level was the worst cos it has the special servants and new builders children, both of which are extra annoying and freaky. Fun to kill though.

Apart from thief....not much. Although I take a malicious joy in killing all of those weird stalked eyed Rakata in KOTOR, and mr no-jaw malak. Both are just wrong in some way.

That and the AWings in TIE fighter. Theres something just extremely enjoyable about blowing about some rebel wookie-lover up. by tricking them into flying into a starship because their fighter is so fast the AI can't always keep up...
