Mirror's Edge, EA's 2008 parkour-flavoured FPS, "fell short" of the publisher's expectations.

EA Games boss Frank Gibeau told Develop, "First-person parkour across buildings is fun, but to be blunt, Mirror's Edge's' execution fell short."

"What I learned from Mirror's Edge is that you have to execute, you have to spend more time on a game to ensure it's polished, and you need to have the depth and persistence of an online game," he explained.

"There were issues with the learning curve, the difficulty, the narrative, and then there was no multiplayer either."

"The key learning from us was that if you're going to be bold with that kind of concept, you need to take it as far as it can go in development."

We'd say Gibeau needs to easy up on the DICE-developed title. Sure, it wasn't perfect, but it was certainly one of the more interesting new IPs of the last few years.

Eurogamer's Christian Donlan gave it 8/10, saying, "For those who can shrug off the contradictions and the limitations, ignore the tearing cityscape and lingering qualms about value for money, this will shove you so deeply into the experience of being in someone else's body, and taking it on a terrifying, breakneck joyride, that nothing else will matter."

Gibeau didn't stop at Mirror's Edge though – Visceral Games' largely excellent Dead Space also came in for a bit of a pasting.

"It made money for us, but didn't hit expectations. We felt like we had an IP that struck a chord, and one that hit quality, but again it missed multiplayer modes.

"So when we re-worked Dead Space [for the upcoming sequel], we looked at how to make it a better idea, how do we make the story more engrossing, how do we build Isaac as a character, how do we make this game a success online."

Dead Space 2 is out on 25th January on PC, PlayStation 3 and Xbox 360, but what of a Mirror's Edge sequel? "One thing I will say is that we won't give up on those IPs," promised Gibeau. "A new idea obviously has a lot of risk attached to it, but if you get it all right it can be huge."

Infamous litigator Timothy Langdell has been booted from the International Game Developer Association for "lack of integrity" and "unethical behaviour".

Langdell resigned from the IGDA board of directors last August, having only secured his seat months earlier in March.

"The Board of Directors today voted to remove Tim Langdell from IGDA membership pursuant to our by laws Article III. Section 6 (b), which states that any member may be removed from membership if the member has demonstrated a lack of integrity or unethical behaviour, as determined by the Board of Directors," wrote IGDA chair Brian Robbins on the official blog.

Langdell's removal from the IGDA coincides with his courtroom loss to EA, which resulted in his cherished "edge" trademarks being stripped from him.

Timothy Langdell and his company Edge Games are best known for bringing about legal action on anyone using the word "edge" in relation to videogames. Future Publishing was targeted for the title of well-regarded magazine Edge; but the turning point was Langdell's pursuit of mobigame's Edge iPhone game and EA's Mirror's Edge.

Mobigame began an internet crusade against Langdell and publicised his questionable correspondence, and EA went on to bring the house down - turning the tables from courtroom prey to courtroom predator.

Eurogamer blew the Langdell saga wide open with Simon Parkin's thorough investigation of Langdell versus Mobigame last year.

A US court gave Langdell until today to phone companies he had previously harassed to tell them he no longer holds the edge trademark. What the repercussions will be, we do not know.

Incidentally, Eurogamer continues to reach out to Timothy Langdell for comment. But I have a feeling we might not hear back this time.
