At the peak of fan outrage against EA and BioWare over the ending of Mass Effect 3, a BioWare Forums user going by el_spiko filed false advertising complaints against the companies with the Federal Trade Commission and the Better Business Bureau.
Improbably, the BBB has responded to el_spiko's complaint with an extensive blog post. Even more improbably, they basically agree with him that the level of player choice in Mass Effect 3 was misrepresented in ads for the game.
The BBB's Marjorie Stephens:
The issue at stake here is, did BioWare falsely advertise? Technically, yes, they did. In the first bullet point, where it states "the decisions you make completely shape your experience", there is no indecision in that statement. It is an absolute. The next statement is not so absolute. It states "your choices drive powerful outcomes". A consumer would have to very carefully analyze this statement to come to a conclusion that the game's outcome is not "wholly" determined by one's choices.
The post may bring a sense of vindication to outraged ME3 fans, but it doesn't have any direct consequences for BioWare or EA (beyond any sales they may already have lost due to the ending controversy).
