Topic on Talk:Digital rights management (DRM)
Having a page for each DRM would work really well, and with a game list on the same page it wouldn't matter how short the description part is. The game list could be given as a separate link on pages like Steam that are already very long.
Ideally, all old static lists like The Big List of 3rd Party DRM on Steam and List of Games for Windows - LIVE games would be generated by the game pages themselves (this will require some template changes).
