I feel compelled to quote the creators of Tomb Raider, after they said that back in the days when they created the first one, all the enemies were animals, as they found that killing humans would be more despicable, but when it came to Anniversary, today people seem to find killing animals worse than other people... Hell, even I do!
On the other hand, I enjoyed cracking the neck of those pesky, annoying wild dogs in CoD4. First of all, they were a pain in the ass, second, they are -virtual-!
Could people just... please stop being offended by ridiculous things? Grow up, darn it..
