For the U.S. copyright was originally intended to last 14 years, with one 14 year renewal possible. The Constitution states the purpose is "to promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries."
Unless you're arguing video games are not "useful Arts", it seems to me most copyright law nowadays is actually suppressing the Progress of Science and useful Arts -- Mickey Mouse is de facto never going to enter the public domain. Just imagine if literally anyone could create Kingdom Hearts for example. People would buy that, it would likely create competition to create the best "Kingdom Hearts" and it would stimulate the economy. The only argument against is that Disney/Square-Enix deserve that money -- which was not the originally intention of copyright!
