Iron Maiden is suing Ion Maiden dev 3D Realms for trademark infringement
Andrei Mincov's commentary on the original article
The question is not whether those who get to play the game will be confused into thinking that the game has something to do with one of the greatest heavy metal bands. The question is whether people will be attracted to check out the game because they thought that it had something to do with one of the greatest heavy metal bands. And if the answer to that second question is yes, then Iron Maiden will likely succeed if they had to take legal proceedings all the way to the end. If the developers have any degree of self-preservation, now is the perfect time to rename the game so that it bears NO resemblance to Iron Maiden or any of its songs or band members. They already got the world's attention to the game. The last thing they want now is to release the game and pay all the revenues it generates to Iron Maiden and their lawyers.
