Alasdair Bachell and Matthew Barr have published "Video Game Preservation in the UK: A Survey of Records Management Practices" in the International Journal of Digital Curation.
Here's an excerpt:
This study looked at the current attitudes towards preservation in the UK's independent ('indie') video games industry by examining current record-keeping practices and analysing the views of games developers. The results show that there is an interest in preserving games, and possibly a desire to do so, but issues of piracy and cost prevent the industry from undertaking preservation work internally, and from allowing others to assume such responsibility. The recommendation made by this paper is not simply for preservation professionals and enthusiasts to collaborate with the industry, but to do so by advocating the commercial benefits that preservation may offer to the industry.
