Freespace 3
FreeSpace 3 is the name a hypothetical sequel to FreeSpace 2 would logically have. Asking about FreeSpace 3 on the forums tends to provoke annoyance from established members, since it has been asked about so many times before.
In 2004 Derek Smart, creator of the game Battlecruiser: 3000AD, and active participator in many online forums, proposed that he would develop FreeSpace 3. This proposal was met with derision from the HLP community; the reaction was such that Derek Smart registered an account at HLP and threatened to sue members of the forum and shut down community projects once he had acquired the license. According to polls, however, the majority of customers would buy the game regardless of Smart's involvement.
Derek Smart never acquired the license, and at present the license is believed to be owned by Interplay.
