does it include the 64bit version?

i know the retail version included a version for 64bit processors that added a bunch of extra details (all stuff that could have easily been done in the 32bit version but that doesn't work as a marketing gimmick for AMD64 processors)

i remember that update too. it was better looking, but still not a better game. but still one of the first 64bit-retail games afaik. some things only could be done in 64bit though. the amd64-update for far cry showed the difference a lot better.
to answer your question a bit... why wouldn´t the 64bit version be included? they didn´t recode it.

while i still am unsure if the steam version includes the 64-bit patch i found my retail copy and decided in the name of science to see if it would even run... did not test before applying the 64bit patch but it freezes up forcing the three finger salute as soon as the logo screen comes up

could be that it's not going to play nice with intel (it was part of the AMD64 marketing after all) or one of many variables
