I bought a copy of Explorer at E-bay. The explorer is a duo combo of civI and Colonization in CD-ROM. You get two games for the price of one, albeit no instructions or manuals or anything else, just the cd. Mind you, my hard drive has a partition, so i'm playing Colonization with the Windows 98 II O.S. not with the XP. The graphics are different from the dos but, heck, I can hear the wonderful music now and the game doesn't freeze after 20 mins of playing anymore as it did in the XP. So hope you enjoy it once you find it, 'cause it's hard to get your paws on a copy of explorer.
