Aliminator: Actually hybrids were mentioned as results of genetic tampering to some extent in Extinction, even though they also came about naturally, and there have been several other games that bring this up I think. Comics like Aliens: Rogue also say that this comes about through genetic manipulation, also. Either way, notice how I said "some" comics and games, not all.
Also, don't start badmouthing Harry Potter. From experience most people who start spouting that it's just a silly kid's movie haven't seen it for themselves. And it's far from a bad movie. The series has more or less received rave reviews for each installment, and deals with some very adult issues. It's not a kid's movie, it just happens to be a fantasy story with kids in it. They're not for everyone, but they are good enough for any age to enjoy. It just so happens that the latest one is better than most of the junk that came out from studios this year. Bringer of Death: Thank you
I'm not trying to badmouth or put anyone down, I'm just saying is all. Take care everyone, and enjoy the weekend.
