I have a way better idea: everything they say before the game's actually released, you take with a pinch of salt.
Do it. Don't buy their games anymore. Leave the forums.
Make them feel it.
"Welcome to your first day of medical school. Thanks very much for paying your tuition fees that keep us lecturers in a job for the year. Now, while some of you may be expecting that you'll be finishing up in 4 years time able to perform medical miracles and save people's lives, we had a straw poll and decided that we'll be taking out the anatomy classes. We're also going to be removing any work involving diagnosis of cardiovascular issues, but we'll show you a couple of pictures of hearts and lungs and that should be enough for the majority of you.
"If you feel that you've been mis-sold this course, and don't think it's living up to what we promised you in the prospectus, please feel free to leave, without complaint, and don't consider any more courses at our university. There's plenty of other idiots out there that'll keep paying us the fees anyway, and defending our institution despite us dropping the ball in a couple of very high profile cases a few years ago involving malpractice suits being brought against us. Just because we advertised something on our syllabus doesn't mean we actually offer it - what sort of moron believes what the advertising tells them? False advertising legislation? Pfft! We scoff at that sort of thing."
Advertising is the means that companies use to generate interest in a product. It's what encourages people to part with their hard-earned money even before they've actually been able to take use of what they're spending that money on. If you took out a mortgage on a house before it was finished being built, and that house had a missing bedroom, no plug sockets, and the roof wasn't there, you'd be in a court suing the hell out of the people that took your money. While a game may "only" be entertainment, and not a necessity, the people creating it are taking money under false pretences, which is just as illegal as a university or a construction company taking your money off you and not providing what you've paid for - the only difference is the cost, but at what point would you start actually taking this seriously? £50? £500? It's all just haggling over something which is illegal in the first place.
