Breja: As always, I don't like the idea of anything being banned. People should just be smart enough not to throw money at this stuff. If they aren't... well, that sucks, but they should be free to waste their money.
Lifthrasil: Unfortunately stupid people wasting their money often finance business practices that I would prefer not to succeed. DRM for example. Or chopping game content into as many DLC and Episodes as possible instead of one full game.
Problem is, if we ban something because it could lead to "bad" business practices, then that excuse can be used to ban
anything. e.g. "Let's ban violent video games; otherwise this could lead to developers creating games containing even more violence."
I dislike the "sins" of modern gaming industry as much as the next guy here, but I'm completely against having them banned. I'd rather live with such practices (and I know I will always find games from developers who don't follow such practices; if not then my current backlog is enough to last a lifetime anyway) that I would prefer not to succeed, than live with the possibility that someone bans practices that I like but someone else prefers not to succeed. I know for a fact that quite a few people
like episodic games or early access; it's not my place to ban them just like it's not their place to ban violent video games that I like but they don't.
Banning should only be done if someone is being hurt directly or mislead, cheated or deceived. In case of pre-orders this is not the case: the buyer is fully aware he is buying a promise that will be delivered on a non-specified date sometime in the future and is willingly paying for it.
