Posters! Game posters! In png/jpg, and in the shop! Game specific collectables! With the rise of 3D printers, this would be cool! Imagine a nice Fallout poster on Your wall, and some figurines. I understand GoG's policy as a digital distributor, but i WISH it was more than that. Also, i'd love some printable box art!
Miaghstir: The installer is split into several files if it's larger than 2 GB, because that's how Inno Setup handles the choice to make larger installers function on FAT32 drives (that file system can't handle files over 2GB). If the game or its installer is updated you'll still have to redownload the WHOLE installer, not just the exe file.
On FAT32 it's 4GB actually, 2GB was the limit on the older FATs, 2GB is also the filesize limit for a non-UDF DVD format. Just trying to be accurate, sorry.;)
