Let us very quickly touch upon a subject, so you want to buy a new game and your computer is fairly new. You go to your local game store or shop the web for a sweet ass game, and you turn the box over just to find "requires Vista". Well that's just great, I need an operating system with this game, well I guess it just means I don't have a good enough computer to run it. That is where you are wrong sir, games like the first person shooter Shadowrun don't virtually have any reason to run on Vista, it causes even more problems than it fixes with the new operating system. I have Vista, but I also have computers without Vista, and I speak for the common man when I say Boo... Boo on you Microsoft with your big fancy computers, white boxes, and Halo Lunch boxes. In conclusion hopefully there will start to be apparent reason why they make such a decision, so all the questions will stop.
