Do other searches on Google for the individual programs in this package and you'll see comments from many other users about problems using XP. GSP (the company who made these games) is gone, and support is non-existant from the new owners. I've tried running under compatibility mode, etc. Most won't install at all and generate .dll errors in the installation applications. Maybe if you have *exactly* the right version of DirectX, the right set of patches, some other Windows 95/98 programs that have already installed some ancient .dll's or whatever you may be able to get them to limp along. Save your money.
(Note that I can see another review saying it does work in XP. It doesn't work on any of our 3 PCs, all of which are completely updated with patches. Like I said, I'm sure there's some PCs on which it will happen to work, probably if they have installed some other old Windows 95/98 game which has installed some .dll libraries or an old version of Direct X or something. I did get one of them working after spending half a day tracking down some Windows 95 files that don't come with XP on which it appears to be dependent, my time is worth more than that. But it plainly does *not* work properly on Windows XP, it was never developed for XP - they've just later added XP to the list of supported operating systems, and it's not supported so the problems with XP will not be fixed. I stand by my original review. Who wants to buy a program to find out if they might be one of the lucky ones for whom it works?)
