The id Software games were placed on an index of controlled titles in the country in 1994, preventing retailers from selling them to minors.
Germany's Department for Media Harmful to Young Persons (Bundesprufstelle) has now ruled that the original Doom games are only of artistic and scientific interest, and no longer of any interest to youngsters, BBC reports.
However, the US edition of Doom II remains on the index due to the use of the Nazi swastika in certain levels.
id Software parent company Bethesda Softworks is said to have appealed to the Bundesprufstelle, requesting that the watchdog reconsiders the status of the games.
The original Doom was released for home computers in 1993. It has since been ported to a range of platforms, including iOS in 2009.
