Johnathanamz: Getting sick of video game publishing companies and video game development companies not renewing their licenses and losing video games into a digital graveyard.
tomimt: At some point re-newing a license just is far too expensive in contrast to the profits. There's no sense in putting millions in license fees if you won't make even a fraction of that back.
And it should also be noted that in many cases renewing the license for company A to keep the old games on sale would mean that company B can't do new games using the same franchise to base it on.
I think this has been the reason why there have been so many Star Trek games appearing and then quietly disappearing throughout the years, as the license has been going from one company to another.
Of course, having newer games made doesn't mean that they are any better than older games. At least in Star Trek's case, 25th Anniversary, Judgement Rites and A Final Unity are still the best ones made.
Having said that, if some company would get a license to do new TOS games, 25th Anniversary and Judgement Rites might be removed from GOG.
