Just a word of warning. Most editions of this game on CD are for 32 bit systems and will not play on a 64 bit system such as Windows 7. You can buy the game direct online (after trying the trial version to make sure it does play on your PC first) that has been updated but it's not available on disc, only by download and only the individual games (which makes it very expensive). Great fun but a disappointment when you find it won't play on your new PC :(
Just check the specs on the pack before you buy as Vista came in both 32 and 64 bit versions.
