Is it possible to acquire the extra content provided without purchasing the game? Reason being I still own the original Fallout, but would love to get the wallpapers, etc.
Also, would it be possible to implement a way to view extra content, even a sneak-peek, before purchasing?

See that it's available, or actually view the stuff, like wallpapers? B/c I can only see where they've got the stuff is available upon purchase and then there's screens to view, but that's all.

Yes, you can see game`s download stuff like Manual (17 pages), Official soundtrack, Hi-res wallpaper, Avatar. But if you want to download (see, examine) them you must buy the game.

Yeah and it's just a sad fact that if someone WOULD be able to get free sneak-peaks people would just start ass-raping the whole possibility - meaning screenshots of the actual wallpapers or other stupid stuff, just to avoid the REALLY low costs at GoG.. IMHO if I buy something for 5.99-9.99 DOLLARS and get so many lovely extras with it... Well the guys who work at GoG and do all the brainstorming should just go to heaven :P (in a good way people!)
