Are you saying that the copyright is held too long?
I personally think so. 20-30 years for the authors would be enough, in my opinion. For company held copyright, it should be 8-12 years, counting from the date of creation - transferring the rights back to an individual would NOT give any extra time
That'd make basically every game and movie become public domain after a decade or so. If you applied 30 years of copyright to everything, nowadays we'd have public access to every game released up to 1994, which means the majority of the SNES and Mega Drive/Genesis catalogs.
Too bad any change wouldn't apply retroactively, so we'd still have to wait for the 2030s to come by before 1940s stuff becomes public domain.
