Indeed! People in here defending this seem to assume that this campaign won't get anything accomplished and that we're stupid and should just swallow it, because it was obviously done for performance reasons anyway, so what could it possibly be that we're trying to accomplish, right?
In fact, this short little campaign has already managed to get Namco's attention and we're now awaiting what will come of it. I personally don't really care if it's an answer involving a late, QA-tested fundamental design decision such as the above or for performance reasons. Of course, it'll be nice hearing it from them, but I do care more that companies realise that fans won't stand for dishonesty of any kind, even if it turns out to be non-intentional and not actually malicious. They're selling a product (one we find generally good), for heaven's sake, and we should hold them up to standards. Even if mere awareness were the only substantial thing to come of this campaign, I'd still consider it successful.
If you deem such a cause unworthy for an enthusiast forum, then I don't know what to tell you.
As consumers, it is not our responsibility to ensure this doesn't become a slippery slope where companies only come to care about graphics because of a few hardcore fans protesting very clearly about false advertising. That's a ludicrous argument, anyway. If that were indeed what companies' community and PR people take away from this campaign, then they'd have to have people working for them who fail at basic reading comprehension skills. I simply refuse to believe that is the case.
