can some one tell me a site where i can find civ 3 conquers for mac to buy.

Welcome :wavey: Sorry, there is no Civ3 Conquest for Mac ... or Play the World either.

The most recent published and supported release is version 1.21g, and you can get it from places like Amazon. If your CD has an older version (mine is 1.14) there's an updater on MacSoft's web site to get to 1.21g. Alternatively I recommend the updater for all Mac releases, linked in my signature. That takes you to 1.29b2, which is an unsupported beta that is file compatible with PC version 1.29f, the last version of plain "vanilla" Civ3 that was released.

We're all hoping that Civ4 will be released for Mac OS. That's due out for Windows late this year, but we may not get it until it's had the bugs splatted by Windows users.
