Oh no, they did not hurt my feelings That needs more than what they did. And if somebody thinks I expect them to pass out the promise of expansions to everybody...well, no, not really even though a promise on its own is cheap. I would, however, expect them to not promise expansions before they are done with their original project. I am also a bit surprised that the people here don't see the difference between a cloth map being added to a Kickstarter goal and a game expansion being added to one.
Kickstarter works by having people put their trust and their money into other people/a company based solely on their word and whatever else they may have at that time. What Obsidian did do, is violate some of the trust people put into them by starting to promise more than they possibly could at this particular point of time. The initial project is barely more than started and already they are talking about expansions based on, as yet, imaginary sales?
I also run my own business and if/when I see someone behave like this I pull out, yes. Not because my feelings am hurt but because my trust in someones initial goal (which is, after all, the one I pledged my money for) disappears with such promises.
