Here is something that will be nice for people at home who want games for their kids, or want to know what may help make their machines better: 1 & 2.jpg
And 3.jpg shows what software (although this is a game company) can add to their installers to better layout where you go for support or information about accounts etc from an easy layout - user friendly versus just Web links in a folder in the start menu.
The game listed actually has a specific installer for Vista, so you don't even see a program folder in the start menu, as it shows up in the game explorer instead.
I think the system rating, while rather crude and simplistic, gives average joe a simple explaination of where his bottleneck may be in performance, and with the rating right on the game section - an indication why his FPS is choppy to play (system recommended is 4.0 and mine is 3.9 at the lowest - which by the way runs fine).
