I just installed games for windwos marketplace and it has a huge huge memory leak on my machine(windows xp). It eats 10megs of ram per second until it crashes lol((gets to about 1.5gigs of ram used). Probably just a windows xp version problem since they probably put most of the work into the vista/7 version. It also might come with all the expansions. Even tho it doesnt say on the page, the picture does show the complete edition box.
