tomimt: ... In the end every backer should evaluate the project well before pledging in. You should always, always try to see through what is marketing speech and what is not. ...
Nobody can really do that and see through marketing speech. What would be the criteria? Everything that is not dead simple and almost already implemented is potentially just mentioned in case somebody falls for it?
I think there was no reason to assume that they would not be able to make the game offline and DRM free. Even an MMO, just simulate the expansion of the universe or strictly separate between a solo experience and a multiplayer experience. It's possible and there are probably quite some examples out there who do it like this.
When the money is low and there is not enough time then you need to cut somewhere. But the decision where to cut is mostly completely arbitrary. The important question whether it is really impossible to have that game with an offline mode remains (unanswered).
And I wouldn't care if they would refund everyone who doesn't agree with this decision. They can make whatever kind of a game they want to make. But don't cheat on the way. This is unethical. Stand to your decisions and give backers a chance to adjust to it. Don't just grab the money and run away.
If their action is legal which is not completely clear than KS is just a donation society and nothing more. The financial risk would be fully only on the back of the backers and the creative freedom of the creators to change their product would be endless. I would not really recommend KS then, at least not for any professional team that could get the money anyway from somewhere else.
It also does not much good to KS itself by not defining more clearly what is expected of creators and under which circumstances a refund should be done.
amok: interestingly (and this is not aimed at you, but is completely as a side-point to the previous discussion in this thread), this can also sum up the discussions with many of the "DRM free" advocates who claim you can not get DRM free games via Steam :)
Good thing I never do this. :) I always only say that most of the most popular games on Steam you cannot get DRM free. And this is true.
