As the topic says, I am wondering what the difference between Fallout 1 Classic and the new Bethesda release as well as Fallout 2 Classic vs Fallout 2 re-release. Any help would be much appreciated. Thanks in advance for any response.

AFAIK the main difference is that that the classic release has some extras such as the Fallout Bible and I believe that they may be the original uncensored version (the censored version can be easily patched to be uncensored). I could be wrong on the latter, but I'm fairly certain of the former.
