Sony absolutely wants you to buy a Playstation. They're running the same strategy they had for the PS1. It worked great then, it worked better on PS2, it floundered on PS3... and ever since then it's been a charade. But it's a charade that prints money. So long as they pretend games are made for their hardware, and it would obviously be ridiculous to suggest running them anywhere else, they can convince you to sink $500 into brand loyalty.
