Good thing! It's infamy to put just some code into a program so you need to buy a new OS!
If you buy such a game and apply such a patch to let it run under Windows XP, you can't really get sued because circumventing an entire OS can't be part of a software agreement.
That's just showing the finger to those profit-driven vultures! And I love it!
Had a choir in my heart and had to kill it to survive.
