It should be possible and practical by default because they’re based on physical freaking media that can serve as its own DRM if companies are really concerned about people simply installing and giving their discs away. Why does it have to be any more complicated than 'if you want to play media installed from the disc, you need the disc'?
"Microsoft isn’t alone in being horrendously vague and unclear about the 'solution' to pre-owned games – implying of course that pre-owned games are a problem that has to be 'solved.' Sony’s contributed its fair share of non-answers to the discussion as well."
