Honestly, this should be a bigger discussion, and not limited to just games. If a software company sells a software license for perpetual use to someone, they should not be allowed to use copy protection mechanisms that prevent the licensee from using it in perpetuity.
If there’s some other technical reason why the software won’t run any more after ten or twenty years, that’s another story. But if they just can’t be bothered to keep running the licensing servers, then they need to bloody well remove the stinking copy protection.
