Abandonia is an abandonware website, focused on showcasing video games and - where legally permissible – known best for its distributing and discussion of games made for the MS-DOS and earlier Windows operating systems. Abandonia also features a music section and an Abandonware List, a slowly expanding database of over 4600 games including information about their publishers, release dates and whether according to the staff's knowledge the software is sold, protected or "abandoned". This list is a sum total of research and inquiries made by the site's volunteer workforce and its users, with sources including MobyGames, Wikipedia and the company registry at Home of the Underdogs.
