What's the difference between Fallout and Fallout Classic here on GOG?

I only have the "classic" version, not the other one actually being sold.
And if the other one is in any way better (like with compatibility) then i would rather want that one, then the one i got now... obviously.

only real difference is the old version you have has goodies (the various game docs that came in the physical copy)

the bethesda release thats sold now just has arena and daggerfall and i hear a few minor changes liek adding in their logo during loading screens , a resolution patch that should be easy to find and use

btw there have been other threads asking this like the below

honestly you're prolly better off with the versions you have now
