Good find, so long as its the original big box packaged PC version that they are supplying.
Along with the Civ1 Atari ST version, its one of the only things I need to complete my all-formats Civ collection, thanks for posting!
With regard to whether they are trustworthy or not, I trust them because they list their address on the site, and besides, using a credit card you are often protected from online fraud.
@Turner - they are chargin $9.99 for the retail box version, $4.99 for a jewel cased version (which i never saw in the shops over here, perhaps that was a US thing.
Im slightly concerned they say that the big box retail version only contains a 'small manual' in the box with a full PDF manual on the CD - this is not how my Amiga version is, that has a massive 100+pp manual.
Ive asked them to confirm its the original and not a re-release, if it is the original I'll be ordering from them.
