Hi,
I'm the project director of Wildfire, a system that has been running for almost two years now and is almost identical to Revive but it targets Crysis Wars:
If they can talk with EA and obtain the permission to continue working, that would be nice.
It sure would be, unfortunately the policy of EA seems to be to ignore all such requests (I myself have sent them one email and two written letters to their legal team and haven't heard anything back- even in the case of Crysis Wars which cannot be purchased digitally anymore). Fortunately for me I live in the UK and the UK's copyright legislation allows the use & distribution of copyrighted works if the copyright owner does not respond within a reasonable timeframe.
It would be great if EA could acknowledge these requests (even to deny them) since in a court of law (if Revive ever got that far) the case would likely be dismissed since EA waited until Revive was really popular before issuing the takedown (aka, they waited too long).
