"Meat Boy is a vengeful, bloody cube of rotting animal flesh. And he smells. After a short-lived fling with Bandage Girl (sympathy dates, really), he became enraged when he was dumped for the tasty and satisfying Tofu Boy. Once Bandage Girl slept with Tofu Boy and saw all that he had to offer, it was bye-bye beef, hello bean curd. Enraged by his loss and lack of ability to compete with the badass that is Tofu Boy, Meat Boy snapped and kidnapped Bandage Girl—because if he can't have her, no one will."

Does anyone else think it's a bit wrong if it's aimed at children?

A month or two after the games release you can pick up most games second hand for around the £10/£15 mark, and some as low as 50p.
If you're willing to wait a year or so it's possible to pick them up new for not much more.
I've probably forked out £200 for a library of around 20 games which I could sell for the same price.
