Well, if you just look at the Strife loading screen, it says, Copyright, Velocity Inc., all rights reserved. Rogue is mentioned as the developer. And the story goes that Velocity hired Rogue to developer the game, after the previous developer they hired to do it quit on them. Rogue did the work as work-for-hire, it was never their game. It was Velocity's, the publisher.
The story is WAY more complicated than that.
Rich Fleider, Jim Molinets, and Brandon James (IIRC?) started working on the idea for Strife at Cygnus Studios, which was affiliated with Apogee in some way. id Software was to be the publisher for this project, just like they had been for Heretic and Hexen.
Cygnus tried to pull the plug on the project, why I don't know (maybe something to do with a competing project would be my best conjecture). There was an internal revolt; everyone at Cygnus pretty much quit and id helped them found a new company - in the same building, and putting in place several of their pals - James Monroe and Tim Willits included - Rogue Entertainment.
Unfortunately id was now heavily preoccupied with the development of Quake to deal with publishing Strife, so, Rogue had to find a publisher for their idea. They found Velocity, Inc, of San Fran. California, previous devs of the Spectre (VR) series and various other lesser known titles.
I suppose as part of the publishing agreement, Velocity demanded that some or all of the rights to the Strife IP be assigned to them. However, then Velocity tanked after its release. Nobody can figure out where its assets went. Were they sold off, or did they slip into oblivion and become orphaned works? The latter seems the most likely circumstance. Rogue survived for several more years but never published their originally planned sequel to Strife since the IP rights weren't secure.
