One relatively positive story: one of my favorite games of all time, <i>Star Control 2,</i> is effectively immortal because the creators released the source code (even if the compiled, debugged, and ported code isn't able to use the <i>Star Control</i> branding, because the ownership of <i>that</i> was more-or-less sold to Accolade when they published the game, and is still a point of contention.)<br><br>But I'm well aware that that is the exception, not the rule; we've got examples like <i>Homeworld: Cataclysm</i> and <i>Silent Hill 2</i> and <i>3</i> where nobody bothered to save the source once the project wrapped up, MMOs where the IP owners sue anybody that threatens to make their unused property playable,  and niche titles that have just fallen through the cracks.
