Tim Langdell, founder of EDGE Games and former IDGA board member, is evidently not a big believer in freedom of speech -- at least, not in respect to the word "edge."
After managing to remove Mobigames' EDGE from the iPhone app store for a few months under the pretense of copyright infringement, Langdell is now going after PuzzleKings' Killer Edge Racing, yet another app to have committed the unforgivable sin of using a word Tim Langdell thinks he has a monopoly on. According to gamesindustry.biz, Langdell is now applying for a trademark for the name "Killer Edge Racing" in order to force PuzzleKings to drop the title altogether.
In a charmingly creative move, a slew of indie devs have decided to protest Langdell's greedy idiocy by using his own whininess against him. Critter Crunch is now Critter Credge, according to the game's official Web site; Polytron recently announced that 2.5D platformer Fez will now be called Fedge, Canabalt is now Canabedge, and so on.
