The fan outrage at EA and BioWare over Mass Effect 3's ending has escalated from complaining on Twitter and Facebook to filing a complaint against EA with the Federal Trade Commission.
One fan, BioWare forum poster El_Spiko, decided that pre-release promises the developers made about ME3's ending in ads and interviews constituted false advertising, and he filed the complaint -- along with a Better Business Bureau complaint -- to "hold the company accountable."
The complaint doesn't have much hope of succeeding, though. Although the ME3 team did make some statements about the game's endings in interviews that turned out not to be true, the FTC is unlikely to consider those interviews "advertising," and the game's actual ads make ambiguous claims about the ending at best.
The Twitter and Facebook campaigning and a petition that just raised thousands of dollars for charity might be a bit more effective in "taking back Mass Effect 3" though: Director Casey Hudson has said that fan feedback will shape upcoming DLC releases.
It's not a complete rewrite of the ending, but it does offer some hope that it might be fixed.
